Weird battery problems - One (M7) Q&A, Help & Troubleshooting

I have had my international unlocked M7 for almost 2½ years now. For the past 6 months or so I have had weird battery problems.
When on the lower half of the percentage, i.e. below 50%, sometimes it drops incredibly fast, and the phone just dies. At times it goes from 30% to nothing for instance. When I add the charger it lists the battery as 2-5% or something.
Nothing gets hot, and I have tried to use the saver functionality. I don't think there are any apps that cause this, I have tried to keep an eye on it.
I have also tried GSAM, but it didn't tell me anything new - I can install it again and post some logs, if that would be helpful.
What I have done:
* Recently I went to a shop and had the battery replaced, since I assumed this was the problem (battery getting old), but it didn't changed anything. There is, of course, a remote chance that the shop screwed up and didn't replace the battery and screwed me - I have no way of telling...
* I have also recently rooted/unlocked/wiped all caches and installed a ROM from here (Eragon), but that didn't change anything either...
My only conclusion is that this must be a hardware problem - am I correct in assuming that?
Any help/tips are welcome!
Thanks!

Battery Drain on G1

Guys,I own a T Mobile G1 Android 1.6 Phone and recently I’m facing some problems. The problem that appeared recently is with the battery drain. before some days ago the battery of my G1 lasted up to 4-5 days, without using Wireless, GPS, and Bluetooth. If I used the mentioned services normally the battery lasted up to two days. But recently the battery is draining too fast. Within 4 hours the battery goes down less then 15% even I do not use any mentioned services. I keep my phone on standby, without talking a single minute with the phone, not using any service etc, and again it goes down very quick. I took some measures according to HTC instructions how to save the battery but again it does not function. I uninstalled all applications and reset the phone to factory setting by again same thing. Then I searched on the Google some instructions, I tried also that one’s but again it does not function. I always used HTC charger that came with the phone but again same problem. What is the strangest thing that after some days the battery gets back and works perfectly for two weeks, which means I use the phone normally without charging 4-5 days. As I operate very well with the smartphones, Pocket PC’s etc I start analyzing G1 and monitoring very closely why the battery goes down, I monitored for a long time the query under the :About Phone-Battery use- and I see there that Andorid OS is using the battery from 76% up to 85%. Now it came to my mind that something is keeping engaged or it keeps running the Andorid OS always on. Then I suspected that thre my be any virus on my phone, but I installed form Market Flexilis/lookout antivirus application, but there was no virus and again the battery goes very quickly down. As I said after sometime the system returns to normal and the battery lasts for 4-5 days, and when I check the information under Phone,Battery use, I see that the Andorid OS is spending only 6% of the battery. Comparing with the previous description it is a huge difference. According to my opinion there is a small problem with any file which keeps always running to much the Andorid OS. Can you please give me any instruction why Andorid OS is spending that much the battery? Or give me any instruction how to prevent this operation that keeps Android OS to much engaged? or is there any programming mistake?, is there any need for update?, do I need to root my phone as it is not rooted? The reason why I’m thinking that there is a technical problem is because sometimes the system gets back to normal and sometimes it goes out of normal running. I appreciate a lot if you could help me to resolve the mentioned problem.
I've noticed the same thing on my G1 sometimes there is fast battery drain and it seems associated with Android OS. The percentage is over 70%. I also notice it be associated with the display as well. Could be that there is some process that won't stop running and is using Android OS or it could be that on other occasions the display is not going into sleep mode properly. I wish I knew how to fix these problems but I don't. I just observe them.
The battery issue, is an up and down problem for me. Sometime I can go through it in one day or less, other days it will last me for 2 plus days.
It also could be that the battery need replacing. Who's know.
I just bought a 2nd hand G1 - works just fine. I rooted and installed CM6.1.
My battery drains within 1-2 hours. I've tried various methods of resetting stats, with no luck. How frustrating! I wonder if it's a battery hardware problem or software?

I also faced bad battery life on various roms. Since I'm using COS-DS (android 2.3.3) http://forum.xda-developers.com/showthread.php?t=950765 and the Biffmod kernel http://forum.xda-developers.com/showthread.php?t=950765 the phone runs more than 24h when texting and calling. Of course you should apply the 14MB RAM hack in comination with this kernel http://forum.xda-developers.com/showthread.php?t=831139. On standby (everything off, except data and 3g) my G1 runs >48h, before it needs to be plugged in.

Sounds like the basic description of the USB Charging Bug.
The bug triggers if the G1 is using a kernel starting 2.6.35 and onward tree, and charged using the USB instead of AC wall charger.
A couple of option to avoid the super discharge after that (you can use either);
1. Reboot after you unplug the USB charger.
2. Change kernel to one from 2.6.34 tree
You can also visit the Dev sub-forum, there's a thread there discussing the debugging process.
It is so unpredictable for me...I have just got into the habit of a reboot after unplugging USB.
Battery drain on the G1
I have the same problem. Even on standby it drops to less than half of its battery life. Sometimes its worse. today i noticed that the battery percentage was at 84. Next thing I know the phone reboots itself and it displays that it has 1% battery, battery icon empty all in red and LED flashing in red. Then I turn it off connect it to the charger, after a couple of seconds I turn it back on and says its 90 something percent. Could be a virus or just a battery bug,that's my guess. I scanned the phone with Lookout Security and there was no Virus,malware or spyware found.
I want to try different kernels for this battery issue but want to make sure I am installing the right one.
I have CM6.1 with 2.22.23.02 radio and DangerSPL installed. Can I just load any of the kernels built for EBI0?
Specifically, can I flash the kernel in the 1st post here? http://forum.xda-developers.com/showthread.php?t=1010932
Thanks.

Changing Battery causes severe problems.

Hi
On Thursday I received a new battery in the post (my current battery life was abysmal) anyway i changed the battery to charge the new one. After starting the phone i had to select a new language etc. and found that a huge number of my apps were giving the a force close errors. I decided to factory reset my phone, re-downloaded the apps and found the problem resolved.
However earlier today i switched batteries again (wasn't sure that was the cause last time) and it has happened again. Any Suggestions on what is causing it and how to avoid it in the future (other than simply not replacing the battery) or how to rectify it.
Fake/Faulty battery.

No the battery is genuine samsung from a reputable retailer.
If you have to select a new language, it probably means your phone's internal battery has died. Try taking out the battery for 5 minutes, and see if the clock is still accurate.
knowledge is Power. Guard it well.

Are you sure you are letting the phone shut down properly?? When you think it's shut down, press one of the capacitive buttons, if they light up wait until phone vibrates and lights go out, then swap battery. Had the same happen to me a couple of times.
Hello! Me and some other people had similar issues. Read this thread:
forum.xda-developers.com/showthread.php?t=1022044
It looks impossible but I start to believe that a faulty (or a cheap noname) battery can cause problems like this.
I have two spare cheap ebay batteries. I always pop the battery out with the phone still turned on and never a problem...

[Q] Weird battery issue, Razr i, after Jelly Bean

Hi all,
I have weird battery issue with my Razr i xt890 and I'd like some help. I have tried googling for information, but there's too much noise and I can't find anything suitable.
I'm asking on this site because I know the people on here are really knowledgeable.
My Razr i (with Jelly Bean) seems to have erratic battery readings. Sometimes it'll drop to 6%, and then go up to 90%, and jump around to points in between. I have even seen it drop to 1% and then go up to 6% (or something like that).
Needless to say, this makes the phone unusable because I don't know when it's on low battery so I can charge it. Furthermore, twice, it has reported low battery and then automatically shut itself down.
I hope someone can help with this, because I'm really stuck. I bought this phone overseas, and I don't really want to send it back overseas for warranty repairs.
So, some history.
Before the issue:
This is a stock Razr i, running Retail GB software. When I bought it, it was running 81.5.31002.Retail.en.GB 4.0.4. I upgraded to 81.5.39001.Retail.en.GB 4.0.4 and it's been running fine until this issue happened. I normally get about 4.5-5.5 days of battery before I recharge the phone.
This is stock software. No root. No bootloader unlock. No custom roms.
The issue:
I charged up my phone yesterday, and unplugged it from the charger at 100% battery. There was a notification that 91.2.29001.Retail.en.GB 4.1.2 was available. I selected 'Later' because I was busy at the time.
A bit later (maybe about an hour?), I went back to the phone and checked for updates, and selected to download the update. After it was downloaded, I noticed the battery was about 95%, and then I proceeded to install.
I figured 95% power should be sufficient to perform an upgrade.
The install took, maybe 10-15 minutes? At first glance, it seemed successful, but when the phone started up again, the battery reading was at 100%.
I distinctly remember thinking 'This is impossible. There's no way it could be 95% before the install, and 100% afterwards'.
I played around with the phone a bit (to try out Jelly Bean), and after a few minutes, the battery reading dropped to 60% or something.
That's when I knew something was wrong.
Since then, the phone battery reading has been erratic. If I plug it into a charger, it takes a few minutes and then shoots up to 100%. Unplug it, and it drops to a low level within minutes, and then goes up and down like a yo-yo. Twice, the phone went to a very low level, and then shut itself off.
I've tried various charging/unplugging cycles, and nothing has worked yet (Although I didn't have the patience to try an 8-hour charging cycle yet).
Please see the attached images to see what I mean.
The graphs are just bizarre.
I also did a factory reset (from the Privacy menu rather than 'recovery') but that didn't help.
At the moment, I haven't tried to root the phone or unlock the bootloader. I am still keeping the option of warranty open.
I can't think of a reason why this is happening. It doesn't seem to be a simple calibration or battery stats issue. I think the battery is working okay (because it was fine before the upgrade), just that the readings are wrong.
The phone is operating okay in all other respects. If I ignore the battery readings and the 'low battery' alerts, the phone continues to work ... except when it shuts itself down.
Another theory could be that ... because I upgraded without plugging the phone in, perhaps there was insufficient power during the upgrade and caused some corruption, and I have a faulty software/firmware? Not sure how I could test that though.
Any ideas, any one? Please?

Jelly bean download issues
Hi, I have had exactly the same problem after downloading jelly bean. It even died when plugged in charging. As I had only had the phone for three weeks, I took it back to the shop, Phones 4 You, and they exchanged it for a new phone and told me not to download jelly bean until they let me know it's safe to do so. They said that it was a software problem. Prior to this the battery life was outstanding and I am very pleased with the phone. Phones 4 You gave me an excellent service.
Fixed!
For future readers ...
Someone on the motorola forums (see second reply on this thread) mentioned a possible solution which was to manually install the Jelly Bean version again. I decided to give this a try.
After some more research, I discovered that it should be possible to manually apply official Motorola (ie. OTA) updates using the stock bootloader (via the bootloader recovery feature). No unlocking, no root needed.
I gave this a try ... downloaded the software (keeping to the same version), placed it on an SD card, went to recovery and selected 'Updated from external card' (or something like that) and followed through ... and it has worked (Although this time I kept the phone connected to a usb cable throughout the upgrade). My battery readings are back to normal again. I didn't lose any data or apps as a result of this 'manual upgrade'.
And I am presumably still under warranty since I didn't root nor unlock the bootloader.
Other readers may consider trying this for themselves, however, I cannot guarantee that it will work for them. I can only say it worked for me.

I don't have the phone yet (supposed to get it tonight) but having read quite a bit it seems Moto suggests a factory reset after upgrading to JB in order to sort out battery drain etc. I think I saw it in the battery stats thread in RAZR i general.
I send my Razr I back to Germany (living in The Netherlands myself) yesterday! Had the same problem, only my battery get down to 0% all the time, so the phone shutsdown itself every 1 minute till 1 houre. (I'm from the topic: Auto shutdown (battery problem). I think i get my new one next week on wednesday. Dus the JB software manualy update works for more people?

I think the problems described in this thread are relating to strange battery spikes in percentage and not a general drain of battery.
The problem is that everyone seems to be different. Some people report these spikes, some people are reporting high drains (which turning off google now or factory reset seem to fix) and some people (luckily me!) have had no issues at all - just an even faster phone
I did do a factory reset, though not immediately after the first JB upgrade. It didn't help.
I think describing this issue as battery drain or high battery usage is not quite correct. The battery is actually okay*, but the phone's indication of the battery capacity jumps all over the place (and sometimes causing automatic shutdown). I can see how it can be confused with battery drain though, especially if people only observe the reading going down (but didn't see the reading going up).
* At one point, I kept the phone screen on as an attempt to drain the battery. I got about 6 hours screen time (ignoring the intermittent battery low warnings) before I gave up.
Since I now have a phone with JB which is working, my guess is that this bug may not occur in all phones with JB. Instead, it seems to be triggered by something that happens during an upgrade.

i have the same problem. factory reset did not help me and i feel i made a mistake i have choosen this phone.i had motorola mobiles before even bought one to my wife.i know that motorola has a conservative atittude.i thought giving them a last chance now i know it was a mistake
Thanks bengtan.
I was having similar issues and a manual install of JB appears to have solved the issue.
Have you had any luck fixing your phone? I have the same problem since a few weeks ago. Bought a new battery and tried two calibration programs, but the issue persists.
Same here. I am on KK 4.4.2 and have the problem since yesterday. What to do?
Same here, my ROM is cm-11-20160524. After 3 years of usage I thought it's the battery and replaced it with a new one but the issue persists.
This is very odd, I'm here after my dad has the same issue and it looks like I'm the 4th poster to report the issue within 50 days after the thread hadn't any replies for over 3 years! Did any of you recent posters resolve the issue? I had a spare Razr-i and my dad took it to a phone repair shop where they swapped both batteries and the issue was still the same with the other battery, so it seems it's nothing to do with the battery itself for all the posters here so far.
Was there some recent update that spiralled all the phones into the erratic behaviour recently I wonder?
I'm trying to advise my dad what to do:
Try fix the issue on his current phone and keep using relatively old tech phone
Use my spare phone (same type) and keep using relatively old tech phone and try sell old XT890 for parts
Upgrade to brand new phone with latest tech and do him for a few years longer than the XT890 would.
Any feedback appreciated!
The issue flatened a bit now. After 2 weeks of brave usage the phone keeps the charge now normally with rare drops in between. So it's still not on an acceptable level but improved magically. I do not understand the physics of this behavior.
I'm having the same strange behaviour since yesterday!!
battery level drops when pluggin the charger,
after several minutes level is jumping to 100%.
whith unplugged charger, level in general inconsistent jumping up and down...!
could this be SW related? planned obsolescence?
edit: android 4.4.2. systemversion 990.43.74.XT890.Retail.en.EU
I have the same problem following an update to JB I don't even recall authorising
I'm now looking for a copy of the new firmware: 990.43.74.XT890.Retail.en.EU to try to resolve. If anyone knows where it can be found I'd be very grateful if you could point me in the right direction...
Same problem here.
I bought a new battery. No changes.
I than did a complete wipe, unlocked the bootloader and installed CyanogenMod 11 (this one http://forum.xda-developers.com/razr-i/development/rom-unofficial-cyanogenmod-11-t2966855). No changes.
I than completely drained the battery (made sure of it) and left it on the charger over night. Now I don't get those weird spikes, the battery just drains really fast (about an hour an the phone is powering off).
Maybe I try a different ROM, or go back to KitKat
I found this but I dunno how to use it ??

Battery issue and restoring completely to stock

Hello everyone,
I have been using a Xperia Z1 for around last 6 months and updated to Lollipop 5.1.1 two months ago. Everything was fine until last week when my phone started to get affected by the battery bug.
The phone works fine and the battery gets discharged in leaps. For example, when I use the phone from 100%, it goes down in the usual way, let's say for 1 hour usage it drops up to 90% which is quite normal. But, when lock the screen and keep it idle for sometime and when I take it back, the battery has dropped a leap, usually by 10-15%.
Yesterday, I was using the phone normally and kept it idle for the entire night and battery has been dropped only from 85% to 79% without stamina mode. That's good. However, when I restarted the phone in the morning, the battery suddenly dropped to 18%. :crying:
I tried calibrating the battery, charging/discharging cycles and removing batterystats.bin. But, the issue is still here.
I think my phone has been affected by the famous Xperia battery bug in Lollipop which means that my battery is damaged. But, before replacing the battery is there anything else that I could do to overcome the issue. Any suggestions are greatly appreciated.
+ My phone is rooted on stock 5.1.1 (14.6.A.0.368) with XZDualRecovery and locked bootloader. If I repair the phone with PCC will it cause any harm or bricking since because of the customer recovery?
Claiming warranty is out of option since the phone has been rooted and flashed with custom recovery.
I don't know why people call it a lollipop bug. There will be a time a battery reaches its end of live. That's what has hit you right now. Your descripte symptoms are from a dying battery. I have seen some dying battery's from me or friends. The battery was holding the charge normally and suddenly no more.
Replace it and all should be fine again.

But, can this happen on a phone that is just 7 months old? Thats what makes me to think that this could be a bug.
I have the same issue, but mine drops to 0% and after waiting some time and booting it the percentage is back up. I have my phone for 2 years now, and the problem appeared in Lollipop also.

It's okay for a 2 year old phone as Lithium batteries wear out with time. In my case, it's kinda disappointing...
So, after searching the entire Internet, I can understand that this is a common issue with Xperia Z1 and Z1 compact and replacing the battery seems to be the only possible solution. I searched EBay for a battery but couldn't choose a good quality one. Can someone guide me on this please?

Your battery is definitely dying and it has nothing to do with roms. Get a battery that the seller claims to be OEM. That's your best bet...

Don't think that it will resolve your problem.
I changed my internal battery about one month ago and when two weeks passed I started to experiment the same bug ? again
It's not only hardware problem, it also software problem, I believe.

You are correct becouse I experience som drops in the range of 5-20% in less than a minute and once 30%. All the time while the phone was in standby mode except once where it did it right in my face (10%). My battery status is reported being fine. I also forced shutdown the phone as per the calibration method for non-rooted phones. Though I did notice dalvik cache wasn't rebuilt and so there is no way to have it refreshed manually except system updates which does this.
Anyway I did remove some apps and did some changes and after this I have not had any sudden drop for weeks. Two of the apps where Truecaller and Facebook official app. Will check though if it was a third one to. I believe one of these or both where playing havok. Especially the Facebook app as it takes liberties I find suspicious, is buggy, can crash the kernel (any app that can do that is doing shady work IMO) and had the addition of a "Video Player" service that was running permanently after you launch the FB app once. I instead use Metal for Facebook now. Pretty much same experience, only 10MB RAM used instead of 90MB and no batter y drain either or any other problem. So in short I believe one of these where the culprits and since many use the FB app that might be the one playing badly with Sony Z1 system.
And If you use Adguard also check if there are apps getting high ratio of ads blocked (or analytics data blocked). Might be some dont get proccessed right in the battery system due to it calculating it wrong. Google Frameworks, Google Contacts, Play Services, Mobilestorage Checker and a few more I disabled the ad filtering for. Though this did not change the battery drop problem previously. It only went away when I uninstalled named apps above.

New battery not solving shutdown problem

Z1 lollipop 5.1.1
build n. 14.6.A.1.236
kernel ver. 3.4.0-perf-gd26777b-00851-ga8b7b55 19 november 2015
It all happened a month ago, after an update, the phone battery registered low and the device reboted, and for the first time in the phone history, I saw, at boot, the "app optimization" dialogue, that kept chewing at what battery life was left.
So, I replaced the battery;
at first start, all seemed OK till I hit an app (whatsapp I think) and the phone displaied the low battery warning and went down.
Same, after a full recharge, when pressing the camera hardware button.
Oh, I also had the discrepancy between the charging icon , which reported 100% charge, and after maybe 10min. 50% and, you know the story.
Now, at the very moment I am writing, after a full charge, 24 hours ago, the phone, without the sim and the SD cards, but left on, registers a charge of 93% (only wireless on, to invite some disharge); of course I cannot check the watsapp, but I took some pics, and the phone stays on.
What do you reckon, I am bugged, as android 5.1.1
should I hang on the phone, which, by the way, performs(ed) pretty well, even though marsmallow is not an option, with the 2GB mem. at least in a bog standard state (i.e. not rooted)?
Thanks
A little update: after two more hours, I started using the browser, and after viewing a couple of pages, the phone swiched itself off.
Now, the charging icon, visible, when phone is off, show a 1% charge.
So, the software battery meter, must be well off the mark?
Last addiction: after an hour, the status light is green (phone charged?) and the charge icon, displays a 100% level.
It's your say, now.
I have this problem and battery replace didnt solve anything here too, but I'm on nougat. I hope someone know a solution for this.. But I think It is some kind of hardware problem.
Little update: after recharging, I switched the phone up and let it play some video on youtube;
well, after maybe half an hour, it went down, and as soon as I plugged the charger in, the icon showed 80% charge, which I allready experienced, dismissing it had a fawlty reading, but, with some afterthought , would be in line with the actual battery drainage ( remember that without any activity it stays on indefenetly) and is, as if, some internal mechanism -either hardware or software, is programmed to switch it off at that precise level.
Just a thought, is there somewhere, the level of battery disharge can be set, at our discretion before the device shuts off, say 15%?
I do not seem to find this specific setting, currently.
It is less credible, as time goes by, to think of it as a specific device/brand problem, given the fact that all the major players ware, seems to be affected, and allowing for differences in platforms, the common denominator would appear to be the software itself.
Exact same problem
Some time ago, I replaced my Xperia SP's battery.
The "used, like new" battery I ordered was as bad as the one that was to be replaced, maybe even worse.
I complained, got another-one. This other battery works great.
Remember: There are no "new" batteries out there, just used-ones.
Some are still good, some are dead.
I don't know where replacement batteries that are new should come from... Sony has never sold them as spare parts. I don't know of any company that produces batteries for Sony phones and sells these batteries on the open market.
I only know of third party spare parts for iPhones. Apple has sold only like 20 different models since 2006.
Sony? More like 100.
Producing third party spare parts just isn't profitable in this case. That's the reason why there aren't any.
Any seller who claims to offer "new" batteries lies. At least if he didn't take them from some never used devices.
I'd be HAPPY to be proven wrong because I also need a new battery for my Z1.
Besides, it's no wonder all our phones' batteries die at the same time. They are all the same age and have had more or less the same amount of charging cycles.
Also, it's no wonder they all die the same way (suddenly empty).
They all (more or less) came out of the same factory.
It's like with cars, same model, same problems.
A Peugeot 206 always has problems with the Zylinderkopfdichtung (don't know the English word, the rubber thingy in the motor that keeps water from mixing with oil), some stuff with the wheels or the exhaust flies off because of rust... for the third time in 5 years...

Some time ago, I replaced my Xperia SP's battery.
The "used, like new" battery I ordered was as bad as the one that was to be replaced, maybe even worse.
Remember: There are no "new" batteries out there, just used-ones.
Some are still good, some are dead.

Your allegations, are worth investigating.

Very important updates.
There seems to be an "xperia battery bug" which kicks in at every battery change.
After having done all the calibration stuff, I re-opened the phone and took the battery connector off, while the phone was on.
Then, did the same, with the phone off.
After three or four days in which the phone did not seem able to start, (rebooted at the first stages of switching on) the phone magically booted up with, and what's more important there was no dicrepancy, between the battery charge level, shown when you plug in the charger, with phone switched off, and the charge level presented by the software, once the phone is on.
So, do not give up your still worth device!
Only thing I noticed now, is a sligtly faster battery consumption, even in stamina mode;
could it be related with the post above?
Maybe a new custom ROM could fix the problem, now that the phone seems stable.
Similar problem.
Phone shuts down when 2 to 3 apps are working simultaneously. It first heats up and then suddenly dies.
Secondly, it sometimes dies on 60% and other days it can work till 1% too. Sometimes after a reboot, it shows the battery percentage abnormally.
I love this phone so i m not planning to throw it away. On the other hand, i cannot find an original battery in the market.
Just chuck a suitable battery in and do the procedure I described.
My battery is not original either, so no problem.
As far as the battery consumption, it seems to be better now, after a week of use.
