[Q] Battery suddenly terrible?

When the battery life of a phone like this goes bad is it a sudden thing? Or does it gradually hold less charge?
I've been using this phone for the best part of 16months with excellent battery life lasting a week with little use. Now all of a sudden it dies EVERY day when I've charged it the night before.
It doesn't even make it through a day at work if I don't even use it at all. No texting, phoning email or anything and it still dies fast.
It can be sat in my pocket all day and then I come to look at it at 6pm and it's off because the battery ran out again
This normal when the batteries start getting a bit old? I thought it would be more gradual, literally 3 days ago it went like this over night.
Anyone else have this problem?

check power settings to see if your auto backlight/power off settings haven't magically been disabled.

Had the exact same problem. Have followed all suggestions available-
making sure wif-fi/bluetooth off
Applications off
internet optimised
battery left to drain, phone reset and new battery fully charged before turnign back on
and several other procedures. 3 new batterys tried including 1 200o battery.
No luck with anything. i get about 6 hours if i dont keep toppoing up. Have to carry a spare battery everywhere.
Has anyone any solutions!!!!????????????

If you are having the issue even with a brand new battery I'm going to guess something's gone wrong with your device.

Not necessarily.
2OP - did you do a hard reset ? If not, do that, do not load any applications, do not change any settings other than the ActiveSync "fake server" trick (which assume you did already), and see if you still have a problem.

For 16months, i think you made the best of your battery life, i think it would be best to replace it as after 400 charge cycles, the battery deteriorates

One other thing I've noticed is that when the battery does run out, the clock has to be re-setup every time. I never had to do this when my phone ran out before. I'm wondering if this is indicative of a probelm other than just a shabby battery.
Thanks,

My tilt 2 had the USB problem (where it (seemingly) charges fine, but it cannot sync).
I noticed that the battery that could go for 2 days with very light use, would not go through more than 1/2 a day even when I don't even touch the phone.
I woud try to plug the phone into a computer via a USB cable and see if the computer recognizes the device.
My phone was under warranty, so when the replacement came, I put in the "dead" battery (according to my defective tilt2), and it listed 70% on the replacement phone.
Anyway, it does sound like you are having the same problem, because you have tried new batteries. So if you try syncing with USB and see if you have the same problem.

All, I seem to be having the same issue with a Sprint TP2. I had the first one replaced thinking it was the device. The replacement arrived and had the same issue. I took it into one of there stores and had the battery replaced. No dice. The battery drains 10% of it's power every 20 minutes, that is with nothing running and me not messing with it. I tried different ROM's thinking that would help. I installed NRG Dinik, GrooveROM, NEO_cht 2018, and Ana CHT. The issue still remains. Yesterday I came across a thread suggesting that I drain the battery completely, the recharge for 5 minutes, powering on and then clearing the storage(Hard reset while the phone is on). Phone charge seemed a little stable in the morning for the first hour, then returned to it's annoying 10% drain every 20 minutes. Any other suggestions?

Left out this folowing information, thought it might be relevant. Also had my charger replaced. Another thing I noticed with this behavior is that the contacts duplicate themselves every so often...

Go to Settings > Sound & Display. Check that the following are turned off:
Quiet ring on pickup
Pocket Mode
I played around with these for awhile and found that either of them, when turned on, will kill the battery in just a few hours.
Also, if you have a Hotmail account set up on it, make sure that it is not set to synchronize "as items arrive." Although you can get away with this setting for Exchange, Hotmail will kill the battery as fast as the above two settings.

3G Search Causes Battery Degradation
Hi,
I wonder if this might help? Maybe I am too late on this. But I recently was having trouble with the very same sudden poor battery issue after using my HTC Rhodium for more than a year with excellent battery life. At the same time I noticed that I was having trouble staying on my cell phone network, also suddenly. This had not been a problem before. Reading the forums in another area discussing signal issues someone pointed to the existence of "CMBandSwitch.exe" which lives in the Windows folder on a standard ROM. When you run this you can switch from "Auto" mode where the phone polls all available network bands and instead have the phone work only on the GSM band. You can also specify your frequency if you wish. When I did this I solved both problems at the same time. My phone once again was able to hold the network just fine and my battery life returned to normal.
I am in Europe on an extended assignment and I can only think that the local network is undergoing some changes that has their 3G signal weak which was causing my phone to work harder at staying attached and therefore creating both poor connectivity and poor battery life.
I hope this will help you.

[Q] Terrible Battery Life - Hardware Fault?

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.

I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.

had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)

Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."

I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.

Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?

So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.

I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!

I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.

[Q] Weird battery issue

Hey guys, just got the phone on Saturday. It's been awesome until today. I noticed it has been draining super fast. I put it on the charger and it would not charge past 89%, and at 89% it said there was 1m left until full. I turned off the phone and let it charge to 100%, but when I turned it on it almost immediately dropped to 90%.
What could be the issue? Do you think a simple factory reset could fix it, or should I take the phone back to Best Buy for a new one?
Edit: using the corded charger that came with the phone

This just started happening to me as well.
My phone will say fully charged, and when I unplug it will immediately drop to ~91-93%. Not sure if it's a faulty battery or what not, as I too have been using the wireless charger and block given to me with the phone.
I'm going to Best Buy during my lunch today to see if they have any idea and will update if there's any useful news.

that is weird. I haven't had the issue on mine, though I only charge with a USB cable (I don't have a wireless pad). From my rooting days, there is a battery config file that remembers things like battery charging history, so a factory reset might be useful, though it's a painful process to get a phone back up and customized fully after a reset.
Hopefully best buy has a better answer...though it might be as simple as replacing the phone, to which a factory reset might have been easier...

Anchor - how is the battery life on your phone?
I think my battery might be a defective one as I can barely get through half of a day with 1 1/2 hours of SOT - and that includes taking several steps to try to maximize battery life.

Just a quick update:
Stopped by Best Buy today and talked to a surprisingly knowledgable Samsung person. He said I'm the second person with an issue like this and believes it's a faulty battery, so they're going to give me a new phone.
To my knowledge this is the only explanation as my battery was lasting half a day.

Same here... I just got this phone yesterday and the battery drains very quick. I will return it and get the htc M9.

Final Update: Battery has been much much better on the new phone. Previously I'd be around 50% by lunchtime and today I'm at 85% with nearly the exact same use.

what was your usge in your previous phone?

Phone shutting off at 35% battery level

Ever since I upgraded to Marshmallow, the phone is shutting off at 35%.
If I plug it into a fast charger it'll start back up. Non fast charger forget it. Battery shows 35% when I plug it in to charge.
Took it to Best Buy after speaking to an AT&T tech. The Samsung rep at BB, said he ran some recovery software to check for missing or corrupted files associated with the upgrade. It appeared that they just reinstalled the 6.01 update.
Anyways it did nothing and the Samsung tech said I could try doing a factory reset or maybe try a new battery. He then said that if the problem started after the the MM update, then that's the issue. He mumbled something about the phone just wasn't able to handle MM blah blah blah.
ATT offered to ship me a new phone with a working upgrade.
Before I go that route or try a factory reset, I thought I'd check here for other ideas.
Not happy with the phone since the MM upgrade. Along with the phone shutting off issue, it's shutting off while charging on my wireless charger, phone screen is screwed up in landscape mode and doesn't show any of the buttons that show in portrait mode.
Is there a battery calibration app that will run on this without root?

I'm a computer tech, with a VZW N4. I popped over here to see if I could help a friend with the ATT N4. Looks like he's stuck without root, but saw your post and decided to reply.
I always recommend installing 'Battery Left Widget' from the Play Store and use it on the main screen. If you want to test the battery... do the following. But I'd recommend getting a new battery. It's most likely the cause of your problem.
Go to the settings and change the 'Discharging Widget Man Text' to "Estimated Battery %". The other settings can be as you wish, but I prefer the 2nd to be time remaining and 3rd to be time dead. Do the same for the charging options.
Let it calibrate for a few days. If you see a big discrepancy between the system battery (in the top right) and the widget, you've got a dying battery. Buy a new one. My Verizon version of the Note 4 started dying at 22% and rebooting. Dying battery was the cause. I knew this because it would read 72% in the top, but 42% in Battery Left Widget. And when it would get to 5% in the widget, it would start rebooting. The other battery at the top was reading much higher. A new battery fixed my woes. However the OTA upgrade to MM did a job on the battery too.
One word of advice ... turn off Fast Charging. It probably killed your battery in the first place. The original Samsung chargers will still charge it to full in a couple hours, but Fast Charging does something bad to the batteries, and they don't last as long. I know, I've had a Note 4 since day one, and I'm on my 4th battery.
A note about MM upgrade. I have to say, I wasn't a fan either. My battery didn't last as long on MM as it did on LP. The tricks about doing a full wipe didn't help. The only fix was to get my VZW model rooted and I regained control. Now I have a MM rom that actually works well and gives me 15 hours a day of usage, 3+ hours of on screen time.

What rom you are using anyway. I have changed my battery and switched to miui 8. But problem remains same with an extended battery life... But mine won't charge more than 67% and shut down @ 12% with a SOT of 3 hours and above.

I would try your battery in another device, just as a test.
Well ... mine is a VZW Note 4, not AT&T. I've used multiple roms over the past few months. I don't know what type of extended battery you are using, but if it's the ZeroLemon, it may need a better kernel to work with it. The phone doesn't know about extended batteries without additional instructions, so charging and time to empty can vary.
I just know I will NEVER buy another Samsung battery from anywhere. I think 99% of them are fake. I went with an Anker brand and it's been perfect.
Currently, I'm running MODest v5 ROM. I just installed Nseven on a 2nd device as a test. As for the MODest ROM, after only a couple of days of testing, it looks like I'll get even better battery life than I did with PaulPizz v2 (over 16 hours of heavy use compared to the 13 with PaulPizz)

Thanks for your quick reply... Im using samsung original Stock battery and there is sticker of smart care and it is from a samsung showroom
So no idea its original or not.. Should have been original... My note 4 SM 910S SK tel korian version so the rom options are very limited. Do not have any warranty period left so im confused whether i should go for a hardware checkup... Anyway im pissed of since the marshmallow arrives....the problem started right after that update.. Since then i have changed rom changed battery.. So now i guess i have to change the phone finally... Anyway thanks for your reply..

I have the same problem with charging to only 67%
If you take out the battery it will continue charging to 100%.
All this cr*p started when updated to MM
Going back to stock 5.0.1 and doing the #*0228# reset should help.
And samsung batteries are a disaster, even the genuines ones.

lg g3 battery % is lying.

I know it's a dinosaur of a device but I've got it modded and it's a good phone and works great. Ok what happens is the battery charges and holds and lasts all day but the level indicator says 100% all the time until the phone shuts down. I've flashed stock firmware from 4.4.2 to 6.0 and 3 or 4 different custom ROMs and it is the same no matter what I do. I have seen it show different battery levels in booting up after flashing something or a situation like that but its a unstable reading because of the way it'll fluctuate. So I'm thinking it's a hardware issue. The phone works as it should with the exception of that. It has a original oem lg battery unknown if it's been replaced or it's got some kind of fault. It's basically my work phone my side chic to my Nexus 6 because the SD card storage holds my music so it would be nice to have that working so I know when it's going to die. Anybody else with this issue. Thanks in advance.

Was the battery ever changed? I think it May be related to battery
G6

That I'm not sure of, it's a oem lg battery and it works good and lasts all day, actually surprisingly very good battery life that's what made me think it was internals because if I reboot into recovery and then back out out when it boots it'll say battery is is dead and shut back off, but I'll reboot again OR just plug it in for a sec it'll boot back up with 100% battery life. It never gives a accurate reading. Well I'll order a new battery off e.bay there only 7$ to 10$ for a original lg battery. It's a great phone for what it is with some mods it's fast as hell.
