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.

Unusual battery drain

Hi,
I know there are many topics on the subject but I didn't find any solution to my problem.
So, since a couple weeks, about when I moved from Europe to the US, my phone drains significantly more battery than before. This has apparently nothing to do with screen brightness, wifi or cell data, since it occurs even in airplane mode during the night. I used to lose about 1-2% during a night, but now it's at least 15%.
You can find a couple screenshots from BetterBatteryStats there (sorry for broken link, it does not work otherwise): n.ethz.ch/~bauera/uploads/Screenshots/
So as I noticed, there are a couple wakelocks but nothing that could explain this large drain. Any idea what could be the reason and how to fix it?
FYI I am using the stock rom 23.4.A.1.232 with Android 5.1.1. Phone model is D5803. The OS was rooted directly when I got the phone in October 2015 and as I said, I did not have any battery problems until recently.
Thanks for your help!
Alex

that's the lollipop battery drain bug on mobile radio, marshmallow should have fix this

Thank you for your reply. However are you sure of that? The bug you are mentioning is apparently linked with mobile data, which I haven't even turned on since a couple reboots at least. Moreover, the battery stats for the night (from the built-in battery menu) show that the mobile network was fully off during that time (airplane mode).

I found this fix worked for me

Thanks for the suggestion! Unfortunately it didn't work in my case, I still lose about 2%/h in airplane mode and screen off.

BBS - Better Battery Stats is your freind. There's also lots of tips in the thread on how to limit most of the common wakelocks.
There are several services in the new Play Services that are keeping your phone awake. With the introduction of wearable bluetooth there are new fitness services that are looking for your wearable devices constantly, disable them and your battery gets better. Obviously if you use fitness bands/trackers then this fix is not for you.
If you have a rooted phone download Disableservice from the playstore, it's a lot easier to use than Xprivacy and you don't need to install Xposed.
Once it's installed, open the system tab, open Google Play Services, then untick (disable) the following:
ConfigFetchService
FitnessSyncAdapterService
GoogleLocationManagerService
GoogleLocationService
NetworkLocationService
ProximitySettingInjectorService
UserPresenceService
WearableControlService
WearableService
WearableSyncService
then reboot your phone.
Disabling these from running should have no impact on your phone, it doesn't for me, and will give you 10-15% more battery life.

Solved Battery drain for Me
I was also suffering from the same battery drain issue, but after doing a lot of research on this forum, few tricks mentioned here worked for me.
It had been 6 days I bought the phone, so was very disappointed by battery life, did upgrade from PC to Lollipop, but still the problem persisted and even worse. So I decided to go back to Kitkat and followed steps here: http://forum.xda-developers.com/z3-c...d5833-t2906706
After downgrade the battery got somewhat better not satisfactory, so I followed the trick of complete drain upto 0% and charge to 100% (switchded off) after reading posts: http://forum.xda-developers.com/z3-c...5#post59797105 by Sydr08 #182
and cache clearing trick after 0% to 100% charge http://forum.xda-developers.com/z3-c...harge-t3207737
After doing 100% charge I turned ON with vol+ pressed but phone did not respond (I guessed that it didn't worked, so switched ON normally) but after booting I found few settings to be reset so I guess it worked
So finally this trick seems to work for me, now the drain has slowed down to a lot extent. I have used phone regularly (calls, games, whatsapp, Music etc), the battery has dropped to 76% in around 8 hrs ( without stamina mode ) just expecting it to last for two days, and more than that with satmina mode.
Firmware: .77 (India)
Model: D5833

Hi Aakm,
As you said, the tricks mentioned so far on this thread were not really effective, at least for me as well. I could live with that 25-30% left at the end of the day (it is still much better than my old Samsung GS2), but I would be glad to be back to the 2-3 days of moderate use as I had during my first months of ownership.
So I'll try this out over the next days and hopefully it will work, thanks for suggesting! It sounds a bit like magic to me but let's give it a try
Best regards,
Alex

Unfortunately the full drain+charge did not change anything for me. I did not try to downgrade to Kitkat but as I've had good battery on Lollipop for several months, I doubt it would help.
Anyway thanks for your help, but I guess I'll simply wait until Android M comes out and take the opportunity for a full factory reset, hoping it will solve the issue.

Please guys mark the star on the bug report, the more people agree, higher will be the chance that google decide that it's time to fix it

Wakelocks

Anyone using battery monitoring apps like BBS or GSam, can you share some of your stats here? I'm trying to figure out whether the seemingly massive amount of wakelocks I'm having is normal or not. The biggest problems seem to be coming from the kernel itself. BBS shows a lot of kernel wakelock time, and GSam consistently lists the kernel as the highest drain in its app sucker screen. Also, the Phone app seems to be waking the device a lot since upgrading to .5.51, which wasn't a problem on .3.374.
I've attached some screenshots that illustrate the problem. I'm already using ForceDoze and Greenify, which have been enabled via ADB, and I've restricted background activity and data for the vast majority of my apps. I'm really hoping there's something I can do about this given that it's impossible to use another kernel (LB and none available for this phone anyway). I've software repaired/clean flashed 3 times.
My battery drain is actually not bad at under 4%/hr (combined screen on/off) and about 1%/hour with the screen off overnight. Today I've logged over 4.5 hours SOT in a period of 17 hours and am sitting pretty at 36%. That's better than any phone I've ever used. But I worry that all the wakelocks are using my phone's CPU, raising its temperature, and might contribute to faster battery degradation.
Also, this is with bluetooth off and my Pebble not paired, but battery drain becomes substantially worse with that setup. My idle drain triples with my Pebble connected. I'm trying to troubleshoot one issue at a time and want to nail these wakelocks before moving onto the bluetooth issues.
If your battery stats looked like mine and especially if you figured out how to fix it, please share!

Given that Sony ended .5.51 deployment prematurely and is currently rolling out .8.49, I think you should update to .8.49 (or wait until your region gets the update if you don't have it yet) then recheck if your problem still persists.
Pouring time and resources into a version that Sony is no longer pushing isn't that great of an investment, especially since it's possible that it was fixed in .8.49.

Everything except the phone app using more battery was the same on .374. And I fixed that after force stopping the phone app and rebooting. I've been trying to troubleshoot this for weeks but just upgraded to .5.51 a couple of days ago. I will flash it when it comes out for Customized UK, but I don't think .5.51 is the root of the problem.
(Oh cool, Xperifirm actually shows .8.49 available for Customized UK now. Time for some flashing!)
Edit: I'm seeing the same degree of wakelocks so far on .8.49.

Update: The battery drain from "phone" is actually Android System. There's a bug in Oreo where sometimes Android System is showing as Phone/RCS in the battery stats. Doesn't explain why Android System is using so much battery though.

So I managed to get a lot of my battery drain figured out, but a few things are still bothering me.
1) Google Play Services and Android System and/or Phone (see my last post) are using the Significant Motion Sensor to wake my device constantly.
2) Sony's smart charger (com.sonymobile.smartcharger) is waking my device. I'm assuming this has something to do with Battery Care, which I find to be a useful feature. But why does it need to continue sending alarms to wake up our phones when not plugged in?
I've attached 2 screenshots from Better Battery Stats showing the first issue (Sensors/Play Services and Phone) and 1 showing the second (Alarms/Smart Charger). Note the "wakeup=true" and long times recorded for Significant Motion. This held true when I had my phone sitting face-down on a table for 6+ hours to do battery testing earlier.
Anyone else who uses battery monitoring apps: have you noticed any similar issues?

I'm with you on RCSService being main culpirt for me. No I don't think it's a bug, it actually does use lots of battery. I listen to 3+ hours of bluetooth music a day and when I saw that RCSService was using more power than my bluetooth, then I thought it was time to experiment. So I uninstalled Carrier Service and RCSService and suddenly my battery life jumped by 20%. There was something in the November update to these services that made them go nuts. Several people have noticed a jump in battery usage, but most people, myself included, thought it was down to the new firmware. Uninstalling these 'features' has made no difference to SMS for me, other than I don't get a read confirmation.
I don't know about smart charger, sorry.
Pretty sure the proximity sensor is always on and that must use some power, but I don't know what that would be called in BBS.

Thanks! I should clarify that when I say it's a bug, I believe something is using a lot of battery, but I don't know that it's necessarily Phone/RCS, because it shows up randomly as either that or just Android System. I think it might be something within Android System but being labeled as Phone or RCS. (Edit: Or the other way around; it could be 100% RCS and sometimes shows up as Android System because the phone is part of that umbrella.) I could be wrong but based my judgment on the links I posted above.
That being said, I disabled Carrier Services on your recommendation in the other thread because my carrier doesn't support VoLTE, VoWiFi, or RCS, I've never seen a "delivered" message, and I don't even use the Google Messages app anyway (I use Texra for SMS and keep Messages disabled). So like you, I don't need these services. And I do think there's been an improvement. Might be time to go through the rest of what you recommended via ADB. The only thing that concerns me about doing that is that I'll have to factory reset if I ever switch carriers and want those services, but I guess that's a small price to pay and an unlikely scenario anyway.
The smart charger thing is just weird. It shouldn't need to constantly check whether I'm charging since it kicks in when you plug in. Yesterday I disabled battery care during the day and re-enabled it at night to charge, and I had the best battery life since I've owned the phone: 4.5 hours of SOT over 18 hours off the charger with 30% remaining. I may have to look at idle drain with battery care disabled. I like the idea of battery care, but if it's draining my battery then it just defeats the purpose.
Regarding sensors, BBS has its own category for proximity sensor; this is a separate sensor for significant motion. Somehow Google Play Services and either Phone/RCS or Android System are using that particular sensor all the time. And not just listening to it, but causing lots of wakeups and doing so while the device is sitting on a table all night. I can only deduce that it's somehow seeing motion when there isn't any.

Do you have 'On Body Detection' enabled in smart lock? That would force the phone to affirm if it's moving/stationary regularly and quite often.

I never enabled that from the start, but just checked in case Google did something, and it's still off.
I also checked my app permissions, and the only ones with access to body sensors are Google Play Services and Tasker. None of my active Tasker profiles require the significant motion sensor. One of them does use the orientation sensor to turn the speakerphone on when it's face-up during a call, but I tried disabling that profile and the stats didn't change.
Maybe I have a messed-up accelerometer...do you know of a way to test that? (Edit: Found it in the Support app - my accelerometer, gyroscope, and proximity sensor are fine)
I think I might head to the Sony Mobile forums with the smart charger issue for that matter. It may be a bug that affects all phones with Qnovo features, or maybe they could at least give me an explanation.

Correct me if I'm wrong, but couldn't you just "reinstall" those services via the same adb commands? Where you typed uninstall, just replace with install?

Maybe, but I don't know where I would be installing them from...? Since I don't have a backup of the package. I uninstalled a bunch of stuff via adb before and it didn't return with a dirty reflash. I had to flash userdata. So that's all I'm going by.

I'm not sure of the actual technical mechanics, but I believe uninstalling system apps doesn't actually remove the package from the system image, so you can reinstall them at any time.
I think it's like taking down a sign on a store, the actual store is still there, just all references to it are no longer there, so to the OS it's not listed - "uninstalled".

I gave up. I still have a ton of wakelocks. GSAM shows a bunch of them even when my phone is supposedly dozing. My battery life is OK, not nearly as great as I hoped I'd have with this phone, but it gets me through the day so I've just been living with it. I have noticed better battery on the latest firmware (July patch) than June. I also got rid of the RCS stuff, which helped a bit. And finally I traced a lot of my drain to an app I was using called "hide running in background notification" which the last few firmwares can do natively.
(Edit: Sorry for missing your previous post!)
Edit: I was sadly mistaken about better battery on the July patch. The battery is only better if I'm not on wifi. I posted in the wifi drain thread about it just now.

Galaxy Tab 2 T519 WiFi and battery problems

Hi,
I have 2 problems with my Galaxy Tab 2 which I hope I could somehow fix with a FW adjustment.
As with many others, the WiFi on my Samsung Galaxy Tab S2 no longer works properly and can no longer be switched on when the tablet is switched off and on again. If the tablet runs out because the battery has run out (0% battery), WiFi will work again after the restart.
In addition, the battery is drained very quickly. I even bought and installed a new battery for this. But I have the same problem there. Overnight, the battery tends to lose about 50% of its capacity even though the tablet is lying around in idle.
That is why I can only use the tablet when it is plugged in because the battery is constantly empty and I cannot switch it off because otherwise the WiFi will no longer work.
A hardware defect would behave differently, wouldn't it?
I tried:
Downloaded the last available FW version of the tablet from Samfirm.
I then correctly loaded the FW onto the tablet using Odin, Download Mode, etc. Unfortunately, it did not fix the problem and I still cannot activate the WLAN and the problems remain.
Edit. It's a SM T819. Sorry for the wrong title.

Note 9 Battery Usage on Wifi

So this is my last resort as i have literally tried everything else already. Recently (speaking a month or so) i have noticed a severe drop in sot on my Note 9 aswell as overnight drain of ~20% with no Apps running. After several tests i have come to the conclusion that the drain seems to stem from having either Wifi or LTE enabled. Now i am aware that both of those require a decent amount of Power in active use, but it does not explain the sudden extreme drain where as before it was ~ 5-6% overnight.
Things i have tried: Replaced the battery, Factory reset, Cache wipe, Disabling all Apps, etc..
The only thing that really worked was disabling Wifi or LTE. Now my question is, has someone had similar issues or can someone provide an App that actually shows Android System Battery usage for Galaxy Devices again? According to the built in Battery Manager Apps only draw about 3% of the 20% that are gone overnight.
Any help or info would be much appreciated.

Bump, really no one who has the same issue?

Try booting your device into Safe Mode and see if that happens. If it doesn't then there is an app on your device that is constantly updating the data to the server and is causing the battery drain. You will have to uninstall it.
