Anker 2050mAh extended battery (same back cover)

Alright so recently I purchased the Anker 2050mAh battery. It's compatible with the T989 (Hercules) and I727 (Skyrocket). It fits in the standard battery cover.
Like my previous Anker batteries, this one arrived with 66%. I used Juice Offender to drain it to 0%, and then fully charged it.
I later used it moderately throughout the day and it lasted about 16 hours. 4 hours on 4G and 12 on Wifi. I DON'T have screenshots though. By moderate use I mean quite a lot of texts, IMs on Facebook, checking Facebook every half hour, about 30 pictures taken in 8MP resolution (without flash), a few quick calls with Google Voice, a bit of web browsing, about 30-45 minutes of gaming, and a few YouTube videos streaming on 4G in high quality.
The next day, I used it on a full charge. The screenshots are attached. I used it moderately/heavily this time. About 3 hours on 4G and 10 on Wifi. More texts, IMs, pictures, 6-7 minutes of HD video recording, streamed more YouTube videos in high quality on 4G, an hour of gaming, some web browsing and dictionary use, and 2 very short calls. As you can see in the screenshots, my phone was awake quite a lot.
NOTE ABOUT THE SCREENSHOTS: The battery isn't at 81%. It really died, and when I put my stock battery in, the battery stats continued (which is really strange) so that's when I took the screenshots. If you look at the chart you can see it went all the way down and then a sudden rise up to 81% at the very end.
Note 2: When Wifi was on, I was using Wifi calling, so the phone signal was turned off.
Note 3: This is on rooted stock ROM + stock kernel, with almost all bloatware removed.
[url=http://www.amazon.com/dp/B0078WR4KW/]Here you can save money by buying two batteries + the universal Anker battery charger. The charger can charge almost any smartphone battery by lining up the metal contacts properly. It can take power by plugging it in a wall outlet or by a USB cable connected to a PC or wall outlet. It can also charge a phone by connecting a micro USB cable from it to the phone. So you can charge two batteries at once.

Awesome,thanks for the review!

This is great.
I used Anker 1900mAh for my sensation and it significantly increased battery life compared to HTC battery. Hope this battery does the same to my T989!
Update: I just bought one. Will try it for few days and update here on how it works!

I'll be watching this thread. I've been wanting to get this, but this is the only review I've found so far.
One thing that caught my eye is that Ankor says "Keep the battery power between 5%-95%", but i like to plug in my phone/battery and just let it charge while i sleep or whatever. I wonder if my habits of just letting it charge until i unplug it will negatively effect the life of the battery.

Things become abnormal when too overly do. I suppose this is the common rule.
Some batteries may not have the "overcharge protection", and if it is not protected, battery life will be shortened. And for me, even if the battery is protected, I will still use it with care.

whoever tests this out, can you guys also use DISPLAY ON TIME and VOICE TIME if you use that. (2 main factors)

What type of usage did you get with the stock battery? At that price I may pick one up.
I'm running an aftermarket rom and tend to get that already, but I'm not too sure what stock debloated is capable of with the normal battery. it's Amazon prime too, so i might order it tonight and see how it does this weekend.
EDIT: Damn, or for $10 more a second and a charger. 2 of my immediate family use this phone.... hm....
Further edit:
would this one fit?

Looks promising.

I got about 23hours on one charge off these batteries

Is it worth it for the extra 200 mAh?
And in the description for the batteries, Anker says:
Using Tips:
- Keep the battery power between 5%-95%.
- Avoid overcharge and over discharge. Please stop charging when the battery is 100% charged.

Thanks for the rude response, but that wasn't the question
The question is will that battery fit the T989. I see the original battery linked says it fits the i727 and t989, but this is listed as the i727r. I don't know the variants of the skyrocket well, if at all, so my question is will the one I linked fit our devices.

I have it and it fits. Comes with funny English......also ignore signature I am using t989

That appears to be the same one I linked to earlier (but listed specifically for this phone at a higher price).

looks good
but i think with my anker as a primary, a charged oem battery as a backup, and a powerskin ready to snap on I should be ok with power... just wish there was an easy way to tune down the auto-brightness on our devices. ive seen roms with it built-in but not sure how

ORdered one thanks for this OP

Woah, nice find man! Im seriously thinking about buying a second battery now. how much is the battery percent increase? 5-10ish%?

[Q] Battery - should I charge straight away, or let it run down first?

I'm not up-to-date on battery etiquette, so thought I would check with you chaps. I should be picking my One X up from Carphone Warehouse tomorrow or Wed, but wanted to know whether it was considered better to charge immediately, or to use the battery until the phone dies, then charge fully, or some other third option. Want to make sure I get the best out of the battery, obviously.
Thanks!

What you really want to do is condition your battery. You don't need to do it immediately but in the first week or so of having the phone. By conditioning, I mean... Charging it until it's full, then using it until its fully discharged, then charging it again. Repeat this cycle ("fully discharged when charging") for 3 to 4 times... after that, you'll notice that your battery lasts longer than usual. It's what I've done with all my phones, seemed to work pretty good.

But were you using Lithium-Ion batteries? From what I have heard, completely depleting the power of the battery actually damages its health.

A lot of the time android will shut down just before your battery is 100% empty, you will find if you try to turn your phone on after its shut down it will still boot and run for 15 - 30 mins, depending on battery age and condition ofcorse. And if you keep on turning on the phone when its battery is very low/empty you will then start to damage it.

How to Prime Batteries
...Rechargeable batteries may not deliver their full rated capacity when new and will require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling these batteries after long storage....

Conditioning the battery was needed with old style batteries.. new Li-xxx batteries don't need one.. and what does an extra 30mins actually mean to you ...
now you can buy original replacement batteries for 20-30$, so if it loses it's capacity after some time you can easily buy new one...

I'd use the battery as soon as you get it until completely drained.
Then perform a full battery charge without use, its best to do this to ensure a full 0%-100% charge.

New to wireless charging

Hey people,
New to wireless charging here, my girlfriend just bought a wireless charger for my birthday. Just one question, when you are charging and you need to use the phone, should I pick it up or leave it there and try to use? I mean, if I keep picking it up to use, wouldn't the constant charging/stopping damage the battery? Please help me out!
Thank you!

No, it's fine. Pick it up as many times as you want. I have different wireless pads scattered throughout my house, office and car, that it will not "hurt" it.

It's probably fine. But if by constant you mean literally every 5 seconds then maybe not.
Also there's a xposed mod to disable the sound every time you put it on the pad if they annoy you too constantly.
BTW it'd be great if I had a techy girlfriend

thanks for the comments guys

AFAIK li-ion batteries does not suffer from any memory effect and they even last longer when kept charged. Battery charge cycles are still there as an indicator of the goodness of the battery from the manufacturer but they are related to a full cycle (eg how much current passes through the battery) but smaller charging cycles shouldn't be counted as full.

Just use the pads no need to "worry" about the battery. In some instances batteries will need replacement, but many replace their devices well before you see an issue.
I don't want to go to e-war about batteries. I am just going by personal experience. I have my N4 still, which my wife uses and still uses charging pad still no issues there either.

Could you provide some references for our edification? I admit I'm not the most knowledgeable on the subject but my understanding is that charge cycling is bad at or near full charge. I don't know that this a problem at lower charge levels (let's say <90%).

I don't have an EE degree but from what I understand newer batteries cycles are a full charge from 0-100. I read something on apples' website explaining this. So charging it twice from 50-100 would be one cycle.

You might be right about the charge cycles, as most things seem to relate to amount of power transferred through the battery, and not 'depth of discharge" but honestly many people I've met who plug their phones in all the time to top up, end up having to get the battery replaced after a year. Apple product, ok no problem they do it free for like 2 years; but I've done nothing but run my batteries all the way down every time and slowcharge every night on USB-500mA (gentler current, kinder to battery, cooler temps, and even a slightly more thorough charge) (just 5% POSSIBLY 10% it's hard to say...probably 5%...I guess I should test this)

EE to charge? No, I'm just saying you might want to think twice before picking up 20 times a day from the pad. Better to get MightyText for when you're at your PC/work to text with.
the google charging pad IS better I would have less issues charging on one of those. However, I'm a cheapie, and use $10 chargers, which heat my phone usually to 40C for a full 0%-100% charge. Not best, but I have resigned myself to the reality of potentially replacing the battery in 18 months if I want the convenience of charging pads everywhere. You might wish to think this way as well. Also, after 18 months, maybe you could just charge it at every opportunity (at that point, who cares, you only need it for another 18 months probably) and that would be enough.

All I know is since 1998 I charge my phones to 100% as often as I can find a charging device. I am the only one on my family plan of 5(the others run battery down daily to~30% or more) that doesn't replace their battery before their next upgrade. So my motto is *Top up every chance you get*.

Worried about unremovable battery

This will be my first phone with a battery I cant replace. Batteries lose a lot of capacity and will be down to something like 75% after 12-14 months. Has anyone got a battery replaced on previous models? How much did it cost? What is the battery capacity loss like in general on HTC phones? Thanks

The battery on my m9 has kept itself together well considering it's a year old. I have flashed the sense 8 launcher and now the battery is as good as when I first got it. I wouldn't be worried bout that mate

I haven't had a removable battery since the a Nexus 5. My Nexus 5 turned into a media player and it holds a charge for about 3 days easy. 5 days when I rarely touch it. It's almost going on 3 years old. I don't miss a removable battery all that much as I thought I would.

You also have QC 3.0 and the HTC charger has some cooling tech, so the battery should have a better lifespan than previous iterations anyway.

the point of having replacing battery is to carry one with you at all times to replace it, right?
I think, if you're gonna carry something i would rather have a power bank, less dangerous to have around and takes way more battery and you don't have to remove the battery to use, yes it has to be connect to the phone, but hey, everything has pros and cons.
I prefer the power bank and i also never had to change a battery because it lost quality, but that's me

No, I replace my battery every 6 months as batteries lose capacity, after replacing it, I always get a big increase in battery life, after 1-2 years, it may only holding 60-70% of original charge

You must be doing a lot of charge and discharge cycles a day to wear it out that quick...

So I've had my M7 since I pre-ordered it April of 2013. Still the original battery. If I unplug the phone at 8am and use it normally throughout the day (occasionally browsing reddit/YouTube, texts/messenger/emails during downtime), it probably lasts 8 ish hours without charging it at all.
Not sure if that helps. Can definitely tell it's degraded a bit since I first got it.

Your phone doesn't get to 100% in 5 seconds with a power bank, a replaceable battery does. A replaceable battery is a lot lighter and smaller than a power bank. And who wants to use a phone with something tethered to it?

if you're using the phone you're most likely not moving a lot either, which means you can easy stay still and connected to the power bank, there are small power banks and some even give you quick charge option, but like i said or meant to say, use whatever you want and think it's better for you

My M8 was purchased on day one and after two years of use it's still going very strong. I don't notice any significant differences from my initial impressions.

How do you calibrate battery?

M7 three years old. Always get 4 hours plus sot. Even got seven when reading heavy. I wouldn't worry, just don't charge all night, buy a timer.

Attached the wrong one, even though it was good too.

Batteries are odd things, especially Li-polymer batteries.
Like above, my M7 is 3 years old.
I get 14-20 hours average out of my phone with a LOT of web/email and poor coverage (mentioned because it sucks more juice in thinner coverage). Currently I'm on 13+ hours and have 17% left.
The real damage to these batteries is # of charging cycles and heat. Heat prematurely wears out the chemicals and each time you plug into charge you're killing one of a limited amount of charge cycles.
You should not see a true decrease in capacity as these don't have memory effect.
I'm a horrible user in that I often plug into charge when in the car and tend to run my battery way down before recharging, both of which are hard on a battery.

When you get a new phone there is not need to worry about this at the beginning, but after 2-3 months you should think about doing a full discharge, from 100% until it turns off, even after it turns off i don't plug it right in, i try to boot it 2 or 3 times and let it turn off by it self again, then just charge it 100% again, this should help is some cases (do this procedure only once a month maybe, there is no need to do it all the time because it will put strain in the battery and if you do it a lot you will also lose battery life).
Another thing to keep in mind is that tests have shown that if you can, you should charge your phone at +-50% (instead of 20% or less) until 90-98%~, of course not everyone has the time for this but it's something that helps maintain battery life.
Battery's also need exercise and keeping the battery plugged in a lot won't help, if you can avoiding stressing the battery with high temperatures as this also reduces the battery life.
There might be a few more tips for battery's but this is all I remember/know for now, hope it helps :good:

Phone abruptly dies under 20% battery

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!
