I purchased the Sieidio Battery 1750mAh on Amazon about a month ago. This battery is not worth the money at all. If you want an extra battery then I suggest buying an OEM battery.
I might be wrong but I think this battery actually goes down faster than the one that came with the phone. My biggest problem with this battery is that it does not fit properly in the phone. It can just be set down or place in my pocket and that is enough to make the phone.
DON'T wast you money on this battery

I don't even understand your review, but I guess I do understand you are being negative.
But this battery works way better than the stock battery that came with my EVO. It ****s on the stock battery. Diarrhea.
Maybe it's just because I bought it for $50 from Best Buy. What a bargain!

Sounds like too much for a 1750 battery. I'd rather just go all out and get the 3500

I got two 1800mAh batteries for about $30, and experienced the same thing. After awhile though, I realized that you have to do a few things to get better battery life.
1) Charge the battery to full while the phone is on.
2) Unplug and plug back in to verify that the phone is fully charged (green led)
3) Turn the phone off
4) Unplug, plug in, and wait for a green led
5) Repeat that 5-10 times
6) Then while still plugged in, reboot into Recovery and wipe the battery stats via the advanced menu.
7) Reboot, and use your phone as you normally would.
This may sound like alot, but it really only take about 5 mins. Even after wipe, it will still take about 5 full discharges to reap the better battery life. Hope this helps!
I think its just luck of the draw on aftermarket batteries (the cheap ones at least)
I have heard good and bad on ALL of them.
I got the Chichitec/htcexpress 1800 batteries with charger. Came in the other day and I couldn't be happier. 14 hours on initial charge, that's unheard of for me. On my stock battery I had to keep the phone plugged in most of the day at work just to still have juice by the time I got home. And supposedly these things start acting even better after a few charge cycles.
(Fits with stock battery door too)
But for every person that has a good experience with any of these companies, there's someone else with a horror story.

Could have told you that before you bought it, ratings by aftermarket reputable companies are close and never accurate...if they rate it at 1750, it's probably 1500-1650... The stock is 1500 so yes you wasted your money. Now on the other hand, the 3500 is the best investment anyone could ever make....
It's been proven long ago seidio over rates their batteries. The "1750" is actually just under 1500, so less capacity then the stock battery.

just terribad in my opinion, gonna stick to my seidio 3500. rather have the size and life than a small size and a measly bump from the 1750mah battery
They rated it less than a 1500 stock battery.
Key with extended batteries is that you actually have to charge them longer than your phone indicates.
Example: I phone said it was fully charged at 3:26am in the morning. Yet it continue to charge until at least 6:45am before it was constant. Granted I am using an SBC kernel but even without, you need to let it charge the night. Don't let the green light fool you. It takes a few extra hours to charge even if the led light is green!
You should just about fully drain your battery and then let it charge overnight. If you aren't on an SBC kernel you may actually want to charge your phone while it's off so that the battery dictates the charge.
You should also wipe your battery stats once the phone is fully charged.
Try that and see if it works for you. I know that I was getting great battery life even on the stock battery. I play "Word With friends" (at least 15 matches running) a lot (at least 15 matches running concurrently) and this game actually drains battery. I still got through the day fine though I also carry a Touch Pro 2 and having the batteries that are the same size allows me to swap when needed.
I have the 2650mah one from sprint and my 3500mah seidio coming in the mail tomorrow. I'll probably write a review for it later. Note, On my 2650mah, it's already on its 12th hour and I was was playing WWF, surfing the web, made several calls and it's still at 77%. I will leave it off the charger tonight and see how it fairs tomorrow.
Good Luck!
I have tested these and if they do last longer then stock, it is only like maybe 20 mins. I have an external charger as well as running the SBC kernel to get a complete charge. I have the sprint 2600 battery as well and love it. Not many cases for it but I have modified a sedio rugged and ballistic to work with it. I let my wife use it for a few days in her evo and had to fight to get it back from her.

Read an article in the HTC Sensation forums where many of the posters picked up an Anker battery as a "Why the hell not for $15?" deal and had generally positive results. Did a search and not only does Amazon sell multiple varieties of Anker batteries, but many of them have a ton of positive reviews.
Before all the battery naysayers jump in and shout "You can't get an extra 300mah in a stock battery! It's another chinese scam and it's probably only 1.03mah!" the Sensation people explained it as being noticeably thicker than the stock battery while still fitting snugly inside the battery door. A good 1mm thicker at least.
Anyway, bought myself a pair along with a car charger for $30 for two batteries, a car charger, and a USB charger. Will let you all know if its a huge letdown, or if the positive reviews aren't just Chinese robots blowing smoke up our you-know-what.
Hey can you do a favor? Install battery calibration app from market and tell us how many mV (Milli volts) it say when the phone is truly 100% charged.
interested in seeing how those batteries are
was about to buy one
keep us posted
I've read in some of the comments on Amazon that they work best when the wall charger is used, though that may be because the wall charger keeps it at 100% while charging inside the phone causes the battery to drain down to 90% if left on the charger after it reaches 100%. Of course, the battery monitor won't tell you that to keep Samsung's support lines from clogging.
Thankfully this is Amazon and not the overseas shipping I had to deal with with my last battery, so it should arrive (according to Amazon) somewhere between the 23rd and 28th. Will test it heavily with my current ROM and let you all know how it fairs.

True. If it's anything like the stock or mugen battery that I have, it'll cap out around 4250 for Froyo, 4200 for MIUI/Gingerbread.
Momax 1700mah is fine and chip.
Well, while discharging the first battery through normal use, I was actually getting a little frustrated that it was taking so long. Got about 24hrs out of it from wall charge to phone shut off, including about 8 - 9hrs of overnight standby.
Got the second battery off the charger and into the phone, and after about an hour it's still showing at 100% and 4100 - 4180ish millivolts.
Anyone, nothing is decided just yet. Will have to see how they hold up after the first 5 full charge and discharges that "sets" the batteries internal memory. Or whatever.
I thought these AOSP ROMS were supposed to drain battery, dammit!
Just about done "Breaking In" the new batteries. Two things: On the surface, they seem to last quite a while given the last time I tested the Mugen battery I was on Froyo and I'm now on MIUI.
From what I've heard, Gingerbread on the Vibrant, whether it's an i9000 leak like Malice or built from the ground up like Cyanogen 7 or MIUI, tends to burn battery faster than on Froyo. I'm also using different voltage settings, a different kernel... you all get the idea.
Apart from flashing back to Froyo, or completely redoing tests on my stock and Mugen batteries on top of the new Anker battery, whatever results I get will be a bit skewed.
Also, MIUI seems to allow the battery to get further down in power before shutting it off. Froyo would often cut me off around 3700, but I usually see MIUI showing battery power as low as 3300 before shutting down.
Your link points to the 2x package...if you look up the batt itself and read the reviews, most will tell you it's basically a cheaper oem replacement
http://www.amazon.com/Anker-1800mAh..._1_5?s=wireless&ie=UTF8&qid=1317360583&sr=1-5
Still a great deal at 11 bucks shipped.... by itself...and assuming it lasts...my original batt that came with my phone died couple of weeks ago... (less than 2hrs on a froyo rom...) had another oem that I'm using now..so far so good, but who knows...this seems like a great buy, but doesn't sounds like it's any kind of gain even with the 1800mAh rating...
Samsung Galaxy SII Touch batteries work in our phones. Tested.
They are 1800mah and can be found for $23 shipped. They are GENUINE Samsung as well so...it WILL be the advertised 1800mah. Just saying.
Even cheaper on ebay : http://www.ebay.com/itm/330601629006?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
Sofiz has the Pisen battery for SGS II 1659 mAh, will this work on the Vibrant?
just ordered one too, hopefully it works out

I think I went over that at least 3 times already. Battery is a perfect fit. Charging is perfect (USB computer and Wall plug in). EVERYTHING WORKS with it. I wish people would read the topic more. It's only 2 pages. . .
Only reason it wouldn't charge in your phone is if you owned a Fascinate, in which case, get out of our forums, punk!
Ordered one from ebay and pretty happy with it so far. Only had it a couple days so far though and still messing around with different roms and kernels so hard to say exactly how long of a charge i get with it.
Got mine today, charging now. Thanks!
Just recieved mine from amazon, and so far its been great !
I bought the two off of ebay that come with the wall charger. I'm getting much improved battery life right now. I'm very happy with them. Even though they do make the phone slightly heavier, it's worth it IMHO.
(Personal opinion here, of course.)
I don't care about battery life. The battery on the Galaxy Nexus is removable. When my phone is dead, I swap out my battery for another one. Two batteries gets me through ANY day, regardless of usage patterns. Batteries are small and fit in men's and women's pockets easily. They fit in glove boxes, desk drawers, etc. They're portable, lightweight, compact, etc. You can take them almost anywhere.
I purchased the Samsung battery charger kit and haven't looked back. Instead of charging my phone and feeling tethered to my charger all day, I use my phone however I want and swap batteries in/out as I need to, and I only charge my phone overnight while sleeping now. The rest of the time, I only charge my batteries through the charging kit.
All these threads on battery calibration, battery life, etc. just seem unwarranted to me. I'm used to toting a charger around with me, so now I just bring my battery kit (usually it sits in my car, not needed) and if my battery dies, I swap in a fresh one and charge the spare with the kit. This way, I can have my phone on me all the time without worry. If I have no nearby electric outlet I can still take along the extra battery and charge both batteries later. I actually have 3 batteries, if I need them (I can't imagine ever using all 3 in a day).
I don't even use the extended battery. Why fatten up my phone, even if only by a little, if I don't need to do so?
This is food for thought, that's all. Does anyone else just use spare batteries and no longer worry (or even obsess, as I used to do with my Thunderbolt) over squeezing out every drop of battery life? To me, life is easier and better this way.
There's a name for the feeling of not being tethered to your charger all day. I call it freedom. It's awesome.

I see where you are coming from.. What do you think of the battery cover? Is it difficult to work with when swapping batteries and will it last with such frequent use? How do you make sure that your spare battery is always ready (I guess you must be in the habit of always putting it on a charger)?
The battery cover is easy to remove. I ordered two spares when I ordered my battery kit (door covers are only $3 each) in case they wear out over time, which I doubt will happen. Many days I don't even swap batteries, as my phone typically lasts 10-12 hours on the regular battery anyway. I do charge my phone in the car (why not? my phone would just sit there otherwise) which is ~30-45 minutes a day, enough for an extra 20% charge mid-day which helps my battery hit the 10+ hour mark. And if it doesn't, I just swap for a new battery.
The spare is always ready because I always keep it in the charger kit so I can grab it when I'm in need. The kit has a light which turns green when the spare battery is charged to 100%. The light is red otherwise. It's quite handy.
At night I plug in both my phone and the charger kit using the Y cable charger that comes with the kit (allows 2 devices to charge simultaneously on one charger). In the morning, I have my phone and spare, both ready to go.
May I also say, I've impressed a few of my iPhone-using friends with my spare charger kit. They always say "I wish I could do that, but I don't have a removable battery." I lol every time (silently to myself...)

I completely agree. That and who is really not near a charger ever all day? Maybe a few but hey that's what changeable batteries is for.
I see nothing wrong with improving what we have with calibration and optimization though...
Lol sounds like you are super jaded from using a thunderbolt.
IMHO your logic is flawed. Why not get good battery life on one or two batteries rather than mediocre battery life on two batteries.
You shouldn't have to carry around two batts just to get usability out of our device. Two batteries is for when you demand extra from your device.
Like when I went to New York I carried two batteries for my BB9700. Not because it was a battery hog but because I was GPSing and texting all day and didn't want to be stranded with a dead battery. I ended up using both batteries several times skipping charging both of them one night.

edit: I get great battery life on this phone btw. I love it and am very happy with its performance.
I do the same thing. Have the extra battery with wall charger and just throw the spare in my pocket if I go anywhere. Like the OP stated I would much rather swap out the battery (if/when needed) and be able to use my phone like I want than worry about trying to conserve it all day.
I haven't had any problems with the battery cover and even if it did I can buy a new one from VZW for $3.25 with my discount ($4.99 retail) so it is a nonissue.
I honestly don't know why so few people do this. And I very rarely even end up using the spare battery, I just like knowing I have it if needed.

Agreed. I read that stuff to be informed, but no longer out of a crazy desire to extend my battery life because I can't live without doing otherwise. It's a nice change.
Again, I'm not saying anyone else has to or should do this. But it makes so much sense to me, and I like to share what works for me to help others who are looking for other options regarding battery life.

I'm a realistic type of guy. What I want from my phone and what I get from my phone are two different things. To believe they are the same is literally delusional, by definition. To complain about X Y or Z company not providing me with what I want is also a bit irrational if I know that, given today's technology's limitations, what I want might be asking a bit too much. We must work with what we have. I have spare batteries. I use them, liberally if I need to, and I don't mind doing so.
I don't expect a 4G phone to last all day while I play WWF, browse the web, text constantly, check and compose emails, take photos, transfer data, and make phone calls. To get 3-4 hours of screen on time on one battery is great (to me).
I think carrying an extra battery is being more responsible on my end for my own admitted usage of the phone, rather than complaining that the battery life "sucks" or hacking my phone to get an extra 20% battery life (although I'm not against this at all - it's just more work overall). Instead of blaming Verizon, Google, and/or Samsung, I'm taking ownership of the fact that I use my phone quite a lot, and I'm fine with carrying an extra battery or two. Instead of blaming others for the battery life of my own phone, I take responsibility for it and I provide my own solution. If anything, I'm speaking of personal responsibility. And in said responsibility I've found freedom from the dreaded phone charger. Again, it's a nice freedom to have.

I agree completely with the OP. A second OEM battery and quality wall dock charger are my second accessory purchase with any of my smart phones. The first being a good case.
Having a 2nd or 3rd (or 4th!) battery and/or a charger around shouldn't be a requirement for using your device throughout the day. Sure if you use your phone hard then you're going to be used to having a charger nearby, but it shouldn't be a req if you're a normal user.
I don't think its unreasonable to expect a normal (12 hours) days use out of a device. FWIW most people are getting that (especially GSM users), and I don't think the battery issues are as widespread as people seem to think. There are "omg batterylife" threads in every new device forum.

I often go a full day without seeing a charger. Sure I could carry one around and hunt for outlets throughout the day, but I don't think that should be a concern. Just want the phone to be reliable.
For what it's worth, I bought an external charger a couple phones back. Just plug in via USB to the phone if it's running low. Really useful when I'm on the train, for example, and I tether wifi for my Xoom. Gets me through the day in a pinch and I don't have to buy a new one with every phone (though I might buy a larger one now given the Galaxy Nexus' bigger battery).
Also, I usually plug the phone in while at my desk and always charge overnight. But I use the hell out of my phone

I have to agree with Martonikaj I'm afraid. Its a phone, just because you CAN swap out the batteries doesn't mean you should HAVE to to get reasonable usage life.

I disagree with the OP for having 2nd, 3rd batteries in order to use it properly based on user usage pattern.
First, define your usage pattern then try to optimize the battery to support that.
My usage pattern requires to have at least 3 and a half our screen time, and charge the phone once every two days, before I went to sleep (or during the night).
And this phone battery can do that without any problem ...
So, I don't need second battery ... and I am ordering the 2000mAH extended battery for GSM model. Having extra 250mAH is nice, it's a bonus for additional 30 minutes screen time! ... while still having the same look and thin device profile
Hey guys can someone recommend a good place to buy a second battery and charger if needed? Is it worth getting the extended battery and do I need to buy a different back cover if I purchase one? I am in Australia so was thinking eBay might be my best bet? Cheers
I do the same as the OP. I have three batteries that I rotate through. The OEM Samsung battery that came with the phone and two 1900mah batteries that I bought from eBay (which aren't too bad by the way) . I don't ever have to plug in my phone anymore because most of the time I have two fully charged batteries ready to go. I get on average between 12-15 hours on a single charge as it is with pretty good use, so I'm not worried about my phone dying, its just more convenient.

Wanting more battery life and having reading a few positive reviews about the Gold 3500, I got one from Amazon (UK). The numbers 3500 vs 2500 mah indicate I should get around 40% extra battery life compared to stock but having played with RC cars and helicopters running LiPo packs I know that pack ratings aren't everything.
Actual battery capacity depends on the discharge rate, the more juice you pull the less the effective battery capacity you get with a lot of energy wasted in heat due to internal battery resistance. Fact of life with batteries of all chemistry.
My original battery is about 6 months old now, charged daily from anywhere between 0-50% remaining. In day to day use the Gold does seem to last longer based on my 6 months experience with the original battery but how much better is it?
I charged the batteries in my phone and turned the phone off once it hit 100% but kept the charger on as it seemed to charge for a bit longer.
Using my RC battery charger, I used the discharge function setting the low voltage cut off to 3V (standard for lithium batteries) and set the discharge rate at a constant 300 mah. Using a constant discharge rate may not be realistic but it does allow for a fair comparison, keep in mind that our phones power usage jumps up and down depending on use.
Results
-----------
6 month old stock battery rated at 2500 mah = 2364 mah (which is what I would expect from a battery with 180 cycles on it)
Brand new Gold 3500 rated at 3500 mah = 2524 mah (a bit disappointing but at least as good as a new stock battery)
Now the discharge rate can make a big difference to effective battery capacity, it might be that the 3500 mah rating on the Gold batteries was determined using a very low discharge rate or they discharged it to below 3V.....or its just a gold wrapper over a stock battery
Interesting to note that the stock Sammy battery is pretty true to its rated capacity, so the perceived increase in battery capacity I experienced with the Gold battery is probably just the difference between a 6 month old battery and a new one.
Oh well, at least I have a spare battery now and didn't pay a fortune for the Gold. The Gold does seem to last a bit longer than the 6 month old stock on so I am happy enough with it.
Notes:
Gold battery had been in use for 2 weeks to run it in
Only one discharge cycle was performed
Could be that I have a dud battery, you results may differ
In real day to day use the discharge properties of the Gold may result in a higher 'effective' capacity
Solar flares are the source of all coding errors
Fairies do live at the end of your garden :cyclops:
It's a shame i've read this post only two days after buying me one of those. Anyway, even if it won't last longer, i'd still have a spare battery right? So everything is not lost
nope, its a shame they rate it 3500mah if this is the case for all.
Mignon, maybe your can get a replacement from thrm and test again. Especially if you have a dud.
Do notice I notoce a significant increase in battery life after charging it past 100%. Probably placebo, I dont know.
Don't think I have a dud, in my experience lion batteries either work or don't. It's not a crap battery, it's just as good as stock but doesn't match the advertised 3500 mah rating.
And it's shiny gold so things aren't that bad

Well that sucks.....haha...i order a gold a week ago.....it should be here soon.....
I got 3500mah gold battery. I review it.
My rom is ultimate rom v5.1, and my stock battery was 11 months old.
Screen on time was always less than 4 hours.
Yesterday I got the gold battery, and I used it up to 1% without first charge, then I charged it 12 hours to initilize the battery.
So unpluged the charge, and tested it as the same usage. I always downclocked to 1000MHz, wifi on, no use 3g data, brightness is zero, bluetooth and gps is off. I downloaded 15 files and apps today, listened to music, did multi windows function, and almost used web browsing.
Now my battery is just 1%. Screen on time is over 5 and half hours. Obviously the battery was improved.
If official JB are released, the battery will be improved more.
But this is not made in Japan. This is made in China because Japanese is so strange on package.
Some of Chinese battery are so dangerous and may be fake, but this gold battery is good one.

I dropped my stock and it works perfectly till 55% then it dies. Gonna throw it away soon. So some of the cells could be damaged. Its not either they work or dont m8.
@Mingnon thanks for your effortful tests.
@eeynjae, what are all apps spreading around those icons in your notification bar ?
I am pretty sure most mobile 3.7v phone batteries are single cell, only the mugen styled battery extender jobs that require a different back cover run two cells in parallel.
Remaining capacity is usually just a function of cell voltage so it's strange that it should just tank at 55%. Battery protection circuits generally prevent discharge past 3.0 volts so not sure what it's going on there.
Either way it sounds like you need a new battery, wouldn't risk recharging a damaged cell...

Remaining capacity is usually just a function of cell voltage so it's strange that it should just tank at 55%. Battery protection circuits generally prevent discharge past 3.0 volts so not sure what it's going on there.
Either way it sounds like you need a new battery, wouldn't risk recharging a damaged cell...

yeah its strange. Stuff started to happen at 50, whrn restarting bat percentage dropped to 10-15%. Without restartingbit would go down normally in beginning. Now after using it some time and dropping it its 55%.
Its definitely it either works or doesnt.
Anyway I dont think it's single cell.
i have the same battery bought it a few months back i'am very satisfied....
it's not a 40% extra time even framework it designed to work with less voltage since after using it below 15% i notice always fake meter value, when you keep your phone asleep for half an hour you will notice an increase in percentage. not accurate but runs fine, its a spare and a great replacement i dont care if it's slightly powerful than stock at least its the same size for 4 extra hours.. i never needed to change case nor a cover of anything its great
Sorry for my off-topic question, but i see in this topic there are advised people recently i bought a noname car charger for my Note, (specs: output 5.5V DC, 800mAh) - is this charger good for the Note or it would damage it? (i read somewhere that the original car charger's output is 5V... this difference of 0.5V has any importance?) Thanks.

Results
-----------
6 month old stock battery rated at 2500 mah = 2364 mah (which is what I would expect from a battery with 180 cycles on it)
Brand new Gold 3500 rated at 3500 mah = 2524 mah (a bit disappointing but at least as good as a new stock battery)

Thanks for your time and efforts - your results are similar to my amateurish measurements performed twice and reported on the other 3500 battery thread. Having no device to test the actual capacity, I just used the continuous video playback in plane mode with minimal backlight. The time to full discharge was almost identical in both cases.

It won't damage your phone, but if you are going to use it as a gps while charging, it will probably keep dranig the battery, 800mah is not enough to charge it while screen is on and gps is running

I dropped my stock and it works perfectly till 55% then it dies. Gonna throw it away soon. So some of the cells could be damaged. Its not either they work or dont m8.

Some of the cells? Its a 3. 7v Li There is only one cell:silly:
i have been disapointed by this type of battery

Why is that?
After i've received mine, i've never ran out of battery during my day. Definitively improved the usage of my phone.
Phone totally goes black/dies when battery is 21% down to 10%. does this just mean the battery I have is bad? What replacement battery is best? I've read Anker makes a good set with charger. Thanks.
Samsung SDI batteries are the only batteries I've known to do this. When screen goes black, that should be a shutdown. Do you plug in your charger at that time? Mine actually actually showed 0%.
It's inconvenient for a battery to shutdown unexpectedly, while showing capacity remaining. I always replace Samsung OEM batteries with another brand. I found one that I liked so l went to Amazon and bought a second plus external charger from same brand. If looking at another alternative, just search MPJ and read the reviews. The battery and wall charger were on sale last week, maybe still.
If you're considering upgrading to sealed battery in unibody phone, you should consider the care required for such a phone to get battery to last. Sealed batteries are actually very similar in capability and ratings; no leap in tech but apparent shortcoming evident in Note7 embarrassment. Fast charging produces heat and steals life from battery's endurance down the road. Studies have shown since lithium batteries have no memory that you're actually prolonging the battery by slow charging without load or minimum load and bump charging rather than cycling battery to near 0% then back to 100%. Manufacturers don't tell you that because they prefer you wear your battery down in less than a year's time and consider another phone purchase.
Maybe Samsung would be better off today if consumers were more aware of how to prolong lithium batteries?
If you want your battery to last two years, bump charge it after 25% used as much as possible; it shouldn't even matter if you bump charge it 3x per day. Avoid fast charging and heat cycles. IOW, try not to use it while charging; the cycles should be short anyway.
Or, if you prefer to abuse a removable battery like the Note 4 and care less, pay about $15 and just replace the battery every year. 500 full cycles is all these batteries are currently rated for due to increased degradation with abuse. Mini cycles allows more of those cycles without degradation but you'll still have capacity when you need it to last a long day without charging.

Wow thanks for all the information. What does bump charge mean exactly? Now my battery won't charge passed 90% either. A different one is on the way.

Try this, if you are rooted and have recovery wipe dalvik cache and cache. Power off phone and pull battery for like 5-10min. Hold the power button (with battery out) for like 1-2min. After letting battery sit out for 5-10min reboot and see what happens. If same instances occur. Your battery is dead just purchase a new one! Anker recommended!

You're welcome.
Bump charging is partially charging before battery gets low. An example would be running the battery down 25% and charging without overcharging it.

Had the same issue, bought a new Anker and issues resolved, the stock Samsung sucks!
I'm just glad there's a way to replace it that'll mean this phone can last a long time if I'm careful with it.
Yeah it must be these batteries. My mom has the Note 4 as well and hers does the same thing. As does mine

Yes the stock Samsung batteries are horrible. They don't last very long then they start misrepresenting the battery statistics to the OS so you get the shutdowns at 20 or so %. I switched to a twenty$ Anker I found on Amazon over 6 months ago and never had the issue occur again. Even thy sprint techs will tell you if you ask them outright!
