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.
Hello.
I'm having trouble with the newly replaced battery on my rooted Xperia Z1 (with android 5.1.1).
2 months ago i replaced the battery because the old one overheated. The new battery has been fine untill a few days ago when it told me all day that it had 50% left. I found that weird so I didn't charge it to let it run out of battery so I could charge it to 100% and recalibrate it.
After the phone suddenly blacked out the battery wouldn't charge any more, so I took it out and messured it's voltage to be around 2.5. So I jumpstarted the battery back to 3.5 V and was able to make it charge again. Even though the battery functions like "normal", it still says 50% all the time with few exceptions which does look to be the correct battery level. The power management app disappears from settings whenever the battery shows 50% and reappears when it shows the correct level.
The battery indicator shows the correct percentage when charging, but not otherwise.
My theory is that there is something wrong with the software regarding the battery management and that it let the battery use too much of it's voltage. I've seen people with similar problems (50% battery indicator and disappearing power management), but the only solution there was to replace the battery. It doesn't seem that likely because of the software being buggy and the battery is only 2 months old.
Here's some screenshots of the weird behavior:

(Couldn't include image because I am a new user)
As I were writing this, it began discharging while hooked up to a charger. Seems to be a bit unstable.
Would appreciate all and any help
Hello!
I also got similar issues. I've read and try anything to find what happened with my Z1.
First, in my experience, some says (on internet) it's Android problem called Sudden Battery Drain Syndrome. I've tried apps like repair battery etc. and calibrator to fix it. Still the same the battery drain badly.
Second, so I am continuing my investigation on internet. I read from xperia care etc and I found that android Lolipop (5.1.1) terribly sucks for Xperia Z1. Many Z1 users confirmed this. Not just the battery problem, there are bugs also, like touchscreen, screen flickering etc.
Third, after knowing this and read like 2 hours to find the solution, I found in this forum that it's better to downgrading the android version back to KitKat or JellyBean. So I installed JellyBean firmware. Just now finished. I hope it'll be good again. I'll inform you.
NB: Factory reset also won't work
Hello, nice to get some response on this thread.

I tried battery repairs, calibrators and so on. Did not do anything for me. After reading up on Sudden Battery Drain Syndrome, I'm inclined to say that it doesn't seem all that similar to my problem.

That is interesting to know. I have experienced alot of those problems. I was thinking about upgrading to a custom unofficial Android 7 for xperia z1, hearing this might be the thing that makes me do it. It's always such a hassle to download apps and set up from a new install, so I've put it off for a while.
Some days after starting this thread, I ordered a new battery. The old one started to do the same thing. Seemed like I could jumpstart it again, but I don't see the point in doing that every other day.
The new battery has been working great for almost 3 weeks now. I still have the Lolipop problems you mentioned, but the phone works as it is supposed to. It acts up from time to time, but I suspect that being because I use Greenify and CPU tuner to make the battery last longer. I might be upgrading to Android 7 and if that fails, I might downgrade.
I'm hoping I was unlucky with the last battery because it lasted so short and that the problem was only related to the battery. I will post updates here if the new battery also suffers.
Hello, I am new here and couldn't find anything similar in the Mi A2 forum about this battery drain in Android Pie 9.0.
I bought the Mi A2 128gb/6gb two months ago, and since yesterday I realised an abnormal battery drain. When I went to check it out, 37% of the battery was spent in the mobile network standby. Today, after 3 hours of use is around 15% already. In my use, I get between 3 to 5% per hour, now it is between 6 to 10% due to this issue, is infuriating for a phone bought two months ago.
I've been since yesterday trying to find a way to discover the cause, I use 4g LTE most part of my day and the signal is good, urban area, in both sim cards.
Haven't used any custom rom or anything, still standard from the global version, did all the updates, including the latest February 25th. I don't think the update is responsible for that, but it is the only different thing I've done in the last weeks.
Have tried several solutions suggested for others xiaomi models but nothing seemed to work.
Did anyone experience this? Does anyone have a solution?
Yes that is pretty strange. Mobile network standby shouldn't be using up that much battery. Try rebooting the phone to see if it resolves. You could install 3rd party apps such as Greenify to monitor background apps more closely/hibernate them, and Naptime which uses aggressive doze to make sure you get better standby battery life.

Download cpu spy and check if phone enter deep sleep, there was a bug some time before with the cpu stuck at 1401mhz.

Thanks for your answer. haven't tried yet rebooting the phone, I did just the network reset and haven't changed a thing.
I downloaded greenify, but haven't quite used because I can't identify an specific app that is causing the problem.
I am using Greenify, Accubattery GSM Battery, CPU Spy as well.
A strange thing is that the excessive battery drain is allocated in some apps.
Usually, in the android battery use, it shows whatsapp and/or instagram are using the most battery, but when you ask the full device, is when it shows the mobile network.
In the GSM Battery, it says the battery used 12% while turned off and 5% while turned on. It makes no sense.
The only thing I could realize is that when it does get in sleep mode, the battery drain stops, but as soon I start to use it again, it returns to happen. I am afraid is a hardware problem.

Thanks for your answer. I downloaded and monitored for today, most of the time it stays in 633MHz, and Deep Sleep. Both together are above 70%.
I don't think is a CPU problem. I am afraid is something with the antenna
I have an update.
I usually use LTE Network most of my day, today I managed to use wi-fi and the problem is not happening.
I suspecting is either an incompatibility with the Mi A2 network. But my girlfriend has the same phone, but the 64/4gb version and is not experiencing this problem, or and hardware problem with my antenna.
Nobody else has experienced this?
So, It has been 10 months of headaches. Bought in july 2019, for two months best phone ever, battery lasted 2 days, near to 1-2% of battery drain at night on standby. After installing miui 11, the battery said "bye bye". 3h screentime, need to charge the phone twice a day, losing 10%/h on standby.
What I tried is:
-havoc os
-xiaomi.eu Miui 11-12. beta and stable
-Evolution x
-latest firmware always/reinstalled latest firmware-vendor
-always clean install wiping everything
-new battery 2 months ago (same results, no difference at all)
-no app is draining battery in the settings
-unistalled analytics and miui daemon (msa not found on xiaomi.eu roms)
the phone goes in deep sleep as you can see in the photos in the link below.
Gps, wifi and bt always on. Tried switching them off, just 1% less of battery drain on standby.
Bought a broken mi 9t pro just to try switching motherboards, just to try that it isn't a electric or physical issue with the phone, but can't do it that right now, waiting the new screen to test the broken phone.

Any suggestion?
Have you tested putting the phone on standby in airplane mode? This is unlikely to be the root of the issue but poor cellular signal may negatively impact the battery life.

tried that also, nothing change. Always 4%+/h of drain in standby.
I've pretty same problem, and it's really strange...
I've a Mi 9T Pro, bought not more than 2 months ago brand new, all stock.
I leave on just the phone active during the night, in both SIM cards: no bt, no wifi, no mobile data active.
The battery drain is around 10%, which is really insane considered that before my 3 years old phone, an Honor 8, in same conditions, was draining not more than 4%.
In general battery is draining really too much.
Passed OTA from MIUI 11 to 12, but the drainage is same.
I'd like to understand what is the issue causing that.
Dude. Same issue for me. It's only 6 months old. I noticed battery loss on miui just a month into purchase. I'd suggest pick a rom without Gapps or one with microG and try them out. I was using evo X and getting around 6-7 hrs SOT. Once I moved to Aim and Omni I started getting 9-10 SOT. I think Gapps is mostly the culprit. Miui sucks these days. I tried miui 12 and was utterly disappointed. Try this and you might just start loving your phone again. I'd say go for Omni and setup microG, install greenify, turn off battery optimisations only for essential messaging apps and turn on aggressive doze. Your sure to see a difference
Try havoc os 3.7 , try it without social apps like instagram, facebook and other crap.
Mine usually lasts around 3 days with 6h sot.
I also have gps , bt , sync and data always on
Tried gms doze? Disabling autostart of apps in miui?
Mi 9T Pro ll Tapatalk
The point, guys, is not to try different ROMs or install apps or not to use social medias because the phone drains battery...
The point is that the phone should not drain battery that much at all!
I think Xiaomi should care more of the firmwares released, trying harder to fix bugs that might be important rather than releasing new features.
My own opinion.
PS. Last night i checked the battery drain thoroughly: from 1.30 am to 7.30 am, just both SIM cards on to receive eventually phone calls, no WiFi, no BT, no internet connection, ND mode active = battery drained 9%
It is not acceptable!!
Clear all apps from memory, clear cache of 'Google Frameworks' and 'Google Play Services' don't restart the phone
I do this whenever I remember usually every few days and get great SOT around 9-11 hours. Although Accubattery says my battery health is 3300 of the 4000 as I've had it for a while and I'm a very very heavy user. Brand new was getting closer to 10-12 hours doing this same method.
I found it by someone posting a random comment somewhere in this forum just don't know who or where I saw it. They gave no explanation as to why it works but just what they did and its worked immediately. Note I'm still on MIUI 11.0.3 Global as I'm nervous this method won't be as effective in more newer MIUI Versions.
If you have a newer version please try and let me know if it still works, hope this helps
Also I reinstall MIUI through the phone after clean flashing it via Mi Flash
That is that I flash clean (erase storage but not lock bootloader) from Mi Flash and then go to the update settings of the phone and then press the 3 dots at the top left and "download latest update" and then install it again
This helped when I was on MIUI 10.X.X but do it out of habit so not sure if it helped for MIUI 11.0.03
edit: Reinstall method
Similar issue with my K20 Pro.
1. The battery backup on Android 9/MIUI 10 was giving me close to 1.5 days of backup of 7-8 hours of screen time.
2. It was decreased to 6-6.5 in Android 10/MIUI 11
3. Now with MIUI 12 it is reduced to 6 hours and with need of charging two times in a single day. All this with no social media apps, only Whatsapp, Youtube, Prime Video, Spotify and MS outlook, teams apps with regular usage. WIFI all the time, no GPS, 2-3 hours of Bluetooth. plus tried deboating MI apps.
So far I have tried PE, EVOX and EU roms but all gave me disappointing battery backup. The battery seems fine only on android pie so my assumption is that battery probably doesn't need replacement and more of xiaomi's firmware related issue on android 10.
It's so disappointing to see such a great piece of hardware holding back because of battery. I hope somebody find a good solution to this issue.
Hi everyone,
I've tested five Android 11 ROMS and I have to say that all of them are fantastic but I always get the same problem: my battery life is decreased 50%. I usually use my rolex device for day-by-day usage. I've tested 5 roms, 3 different batteries for almost 2 months...
Finally I've came back to android 10 (Superior OS is my favourite ) and battery life is normal again... so for the moment I conclude that there is a problem with android 11.
I've read about battery issues with other devices (Samsung) and Android 11, but I don't know if that is a officially known problem or not.
Someone else with that problem?
It doesn't matter what you configure or your ussage of the device. For me my battery is consumed 50% quickier. I've observed that Android doesn't detect any problem with battery or apps or processes, everything seems to be normal. Even at nigh with no usage, screen off and suposed to be sleeping, the battery consumption is very very high

Can you say which ROMs did you tested
Hi Thago,
I've Tested Pixel Experience, WaveOS, ShapeShiftOS, DotOS.
I'm testing PixelExperience_rolex-11.0-20210213-1852-BETA-UNOFFICIAL and when the screen is off, its fine. It can last the whole day, but with the screen on, it last only 3 or 4 hours.

How? Do you mean this?
Use your phone until the battery dies. Wait until the screen turns off completely.
Turn your phone back on. It will likely shut down again before it finishes booting, but the battery isn’t completely dead yet.
Repeat this process several more times. Power it on, let it keep trying to boot up, then let it die. Eventually, the phone won’t even try to boot up anymore — you won’t even see the boot logo or splash screen. At this point, you can stop powering the phone back on.
Without turning your phone on, plug it into a charger. Let it sit there plugged in and turned off for at least 6 hours. The goal here is to charge it to 100% capacity without turning the phone on.
Once you’re confident that your battery is fully charged, go ahead and turn your phone back on. Resume your normal usage and normal charging habits.
I also have problems with battery duration on android 11. I thought the battery was old, but after buying a new one I'm back with the same problem.

Dear Leodp
With latest roms, the battery problems was solved for me. I tested Aosp extended, Superior OS (phoenix) and for me the best: Nusantara OS, I'm testing it for day by day usage for 3 weeks and works really well.

Thanks, Nusantara OS is ok, no battery problems. I also installed Magisk GMS Doze module, which should reduce battery usage for play services.

Hi,
I think I wrote something not 100% correct.
The fast battery drain I was experiencing with some Android versions seems to be due to an app, probably for reading emails, and not to Android itself.
After cleaning up the mess of installed apps, I have now long and consistent battery duration with both Android 10 & 11 (various versions).
There's only (probably) a marginal loss of battery % in Airplane mode on my actual Android 11 installed system, but it's too low to be sure.
So that means: no issues with Rolex and Android 11 for me.
