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.

Problem after flashing Angry ROM v4,2

I love the Angry Team rom v3.6 no issues whatsoever. But now after flashing Angry ROM v4.2 I am feeling certain issues which are very isolated incident (not reported by any of the users so far, i guess). And the bugs are
1. The charging has just gone mad. I would charge it for 100% but once rebooting the phone says that there is absolutely no power or very less (~10% - 15%). Actually I tried to wipe the battery stats, but I could not able to find that option in Philz's Kernel. Can any of the techies help me on how to wipe the battery stats and how can I get the proper stats and correct battery level again. This is very annoying for me, because I dont know even if I see the phone is fully charged, it still may not be so actually.
2. My Note phone mysteriously flickers and automatically shuts down as such flickering intensifies. If I try to connect the phone immediately to charge the flickering stops and be stable for the next 30 mins. This flicker happens even when there is sufficient charge in the phone.
3. At times I see the phone gets hanged.
3. Contacts have a horizontal stripe at top making it difficult to read the recent dialed numbers. (Probably an issue in ROM or something needs to be changed).
Any help is greatly appreciated.

After revert to stock there is massive battery drain.

Hello guys,
I have the follwoing problem. I was on nAa14 with the latest MiniCM, but I started sufferring from massive battery drains from Android System and I decided to go back to stock to see how it handeled.
So I did using SEUS but then the following thing happend. Every time I have data, or Wi-fi on, the battery looses it juice. In a few secounds the phone gives me the 15% message, then 9% then 5% and it turns off.
If I do not touch it (i mean turn the data and wifi off), the phone gives me nearly 2 days battery life with making a fair ammount of calls. I tried a secound time and reinstalled the stock rom via SEUS but there was no change.
Could this be caused by a leftover file from nAa kernel or MiniCM.... Some new driver or... I don't know as I am a potato and a noob
Please help.

[Q] [HELP] SoD keep bugging me after all my efforts

Hi guys!
I've been experiencing some SoD (Sleep of Death) episodes about 3 weeks ago. I've been searching for a solution ever since.
Specifications:
Phone: Samsung Galaxy S i9000;
ROM: currently stock 2.3.4 - I9000XXJWQ
Problem:
-phone keeps shutting down by itself, regardless of what I'm doing. Sometimes, when I reboot, the battery level shows 4-14%. After a second reboot, the battery shows the normal level of 60-70% (the level that was shown when the shut down occur)
-drastic drops on battery levels (screenshot attached - I've been experiencing some more drastic drops than that)
Tried, but no results:
1. I tried other ROMs (6 of them), from JB to KK (Cyanogen McKay SlimBin etc. found on xda) +wipes
2. I tried other battery - still my phone shuts down itself
3. Flash stock kernel and ROM with Odin
4. Battery recalibration didn't work either- I don't know if I made it correct. Read here a post about it and I understand that wiping batterystats.bin dose nothing but clearing the history of the battery consumption. Also, I think that flashing stock ROM took care of wiping that file so no need for calibration (correct me if I'm wrong please). Also, I think trying another battery excluded the possibility of a faulty one.
5. Checked the connection between the phone and the battery. Also I've wrapped the battery in a paper to make sure it didn't move. The phone shutting down even when it stud still on the desk made me think it was not the problem.
6. Wi-Fi setting about sleep: From "Never" to "When screen of"
Q: What do I do next?

[Q] Galaxy Note becomes unresponsive, heats up, and drains battery when idle

Hey Everyone! Want to share with all about this problem i have been facing.
This GT-N7000 of mine has a very strange problem that has been bugging me since the beginning.
Be it using stock ROM (the days of being in totally stock ICS and jellybean ROM) or now, when i use CM11 4.4.4 (Created by the nice people here on XDA and cyanogen), if i leave the phone idle (e.g screen locked and turn off, when i don't use it and place it in my jeans pocket or lying on the table), once every few days (basically whenever the phone feels like it), when not connected to the charger, it will:
1) randomly decide to become unresponsive (means you can't wake the phone up when pressing any physical buttons or touching the screen)
2) Phone becomes hot while in this unresponsive state (I assume the processor is fully utilized, but doing something totally irrelevant and silly)
3) Need to do a battery pull before you can turn on the phone again
4) Notice upon boot that x% of battery was used up. The battery stats would indicate a break, and sudden drop from 72% of battery to 48% battery.. In other words, it seems the phone does not know what it was doing when it was unresponsive. The faster you catch the phone in this state, the more battery you'll have left. if this happens and you didn't catch the phone in this state, the phone would happily guzzle all the life out of your battery, to 0%.
Now that i am rooted and running CM11, i Digged a little deeper, and it seems that after each unresponsive state reboot, setCPU will indicate that there was alot of CPU usage at 1.4Ghz. At first i didn't bother about it, until i remembered my CPU settings was only supposed to run at 500mhz Maximum when my screen is off, or at 1Ghz when battery is below 80% and screen is on. My CM11 kernal is standard kernel and has NO overclock/underclock.
This means the phone somehow managed to overide setCPU while being in unresponsive state and remain clocked at 1.4 ghz even though the screen is off, thus draining the battery extremely quickly and becoming hot
I have tried multiple factory resets with Stock rom, then Re-flash stock rom with ODIN, to changing to CM11 ROM, and i still have this issue. I do not have a sim card Or SD Card plugged into this phone. (Even with sim card/sd card connected, it still has this issue)
Any other users that encounter this? And has anyone found a way to solve this? Thanks for your inputs!
