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.

Galaxy s battery dead our something else???

Hi guys,
yesterday my galaxy s running darky's rom 9.5 shut down for no reason and when I attempted to turn it back on I got the thinking icon then an empty battery graphic then black screen. So I plugged it in to the charger and after about 10 seconds I had the full battery graphic (my battery should have been full.) So I then take it off charge and turn it on, now it will boot and run for about 5 minutes then turn off again. Dead battery I hear you say? To test that theory I put my battery into my friends galaxy s, it works fine, fully charged with no issue. His battery works fine in my phone. Both work for about an hour. Then I swap back. Battery works in my phone this time for around 20 minutes, then same problem as before.
So after this massive story is my battery just stuffed and doesn't want to work with my phone anymore or do I have another issue??
P.s during this whole process I have reset battery stats and done a factory reset all with no result.
Thanks in advance

Sometimes bad contacts in your phone.
And sometimes motherboard problem...
I hope it's the first one!

First check would be the rom /Flash base Froyo with pit 512 and repartition checked should wipe a bad rom .
jje

ok so just a bit of an update, tested some brand new batteries and none worked.
will try updating the .pit file.
also phone will not go into recovery mode when not plugged in but will go into download mode using 3 button method.

Its not an update of the pit file .Stock rom and wipe of battery stats and two weeks use will show batery bad or not .
The rom you have has multiple bad battery posts .
You could always ask Darky for a fix .
jje

Currently have a stock rom running and so far so good.
Hope it works.

having same problem. running liquid smooth rom on tmobile. I was using gps and phone just shut off. Now when I try and turn it on, galaxy s4 comes up then shuts off. I plugged it in to turn it on and now were bootlooping..
Cant get into recovery either :crying:

OK, finally got into recovery mode. erased erased erased. restored, and everything seems to be running smooth so far. I just wonder what the issue was with my phone not coming on. I tried the card trick. Didn't help, so I am guessing the battery connections were fine. Hopefully isnt a motherboard issue..
I haven't had any issues with the rom either at all it works great with my phone and is super smooth, but I don't think the rom would have anything to do with getting into recovery when powered off.
2011... nice lol. Wrong thread! Just trying to search for answers

[Q] Battery issue

Hey guys. I have one problem with my GT-p1000's battery. The tab was bought in UK in february and it had XXJK5 (November 2010) rom flashed in, also i haven't flashed any other roms yet.
So the problem is:
I use the wall charger to charge my tab and I usually plug it when I go sleep.
By the 19th of may it kept the charge well about 12 hours of intensive usage (web surfing via 3g/listening to music/playing HD games etc.) and I was satisfied enough.
But 3 days ago it started to claim constantly day by day on 47% that the battery is very low (1%) . I tried rebooting it time after time, deleting batterystats.bin file using root explorer, even full drain of battery up until it had no power to start and full cycle charging then, but all these attempts gave no result.
In other words, the battery suddenly drops from 47% to 1%.
I have no idea what to do in this case. Any suggestions?
P.S. Don't suggest me to flash newer rom, because it won't help to solve the problem. A friend of mine had the same problem with his tab and he tried a lot of different roms to flash, but it didn't help. He couldn't find any other solution and he finally sold it.

Sorry mate, i have the same problem. I can't use my Tab longer then 3 hours with very mildly use. From 80% to 3% in a flash, shutdown etc.
I tried lots of roms, resetting/deleting battery stats, touching the screen while turning on the tab, nothing helped.
The only thing i did not try was opening the Tab and remove the battery from the mainboard for a while. Some people say that helped. I could not find the right screwdriver so i just sent it to a repair center. I hope they will find out what's wrong.

Hello,
I had the same problem too, wiping battery stat did not help.
Flashing to Overcome v2.0 rc1 helped some people
but what I did was open up the tab with a tri wing screwdriver and unplugged battery for 30 mins and then plug it back in and it solved the issue.

hi guys, i'm getting really pissed off right now
i''ve got my phone for 3 months now and it worked like charm till the last month
every time my phone shutdown randomly , and when i restart it, my battery level is under the 10%

sometimes it doesn't even turn on anymore.
i can't use my phone now only when its charging because it doesn't shutdown then.
I've tried everything that i could think of, i've recalibrated the battery , installed different roms but i got the problem with every rom.
i've even tried it with a ics rom but still got the same problem
someone please help me

I have the exact same problem, am about to buy a new battery tomorrow unless someone else has another solution? This might not be the proper forum but in here at least many i9001 users will read it.
I've had this problem for about a week, was very annoying while on holiday. I've tried using BroodROM BE 1.0, Stock KQE and now back to stock KPG.

Try ebay - you can easily find decent batteries for 5$ there.

Well yes I'm going to try a different battery soon but the odd thing is after my battery charge seems to drop down to 5% or so, it starts charging to about its original charge level without a charger connected. So it's basically 80%->drop to 5%->charge back to 60% without charger.

i'll try now to do a hard reset, go back to stock rom, then reinstall an costum rom,
will tell you if it works!

Plz mods remove/delete this sheeyat.. this is
Galaxy S Plus I9001 Android Development

i have used TeamWin Recovery for wipe all partition becouse with hard reset don't wipe /system and internal sd.

I thought I was the only one with this problem. I charge my battery to full and it starts draining normally. Then, when around 30-80% battery remaining, it turns off. It only turns off when you use it for a while, when the screen is off it stays on normally. After rebooting it turns off within a minute or so. This continues for a few reboots with the battery level remaining roughly the same. Eventually after a few boots it shows 3-4% of battery, after which I of course have to charge. Also tried calibrating and tried different roms but it still remains. I ALSO SWAPPED MY BATTERY WITH A FRIEND BUT IT DIDN'T HELP! It worked like a charm for him but I still got turn offs with his battery.

If i were you Guys, i would install stock rom and hand in my phone under warranty ( of course if you still have it ). Because if this occurs even when u swap battery, let samsung play with you phone then

Its not your battery..restore your phone to the way it was and give it to samsung

i'm getting pissed of now, even with the stock rom it randomly shutsdown.
i don't have any warrenty so i can't give it back to samsung

In case anyone's still wondering, in my case it did turn out to be a fried battery. If anyone else is experiencing the same issues I was, just check your battery to see whether or not it is swollen. If it's bigger than it should be, that probably means it's fried and you should replace it. I'm happily running custom roms without any trouble again now, and battery life is awesome!

Sorry Rajito, but you are having a serious problem, i think the motherboard is the problem, my friend had the same problem with his I9000 S simple. You shoud go to a service !

Hi guys,
I also have this problem, my phone randomly turns off and when I turn it on, it shows much less remaining battery percentage than before. (please see attached image) After turning on the value is increasing, sometimes from ~5% to 30-40% or more...
Now I have CM10 Jelly Bean flashed, but CM9 did the same sometimes but much more rarely than on JB. Today the phone 'died' three times until noon.

Yeah that's the exact same problem I had. In my case it turned out to be a fried battery, see if it's swollen or not, if you lay your battery on a table it should stay still and not wobble around. If the battery's not flat but swollen that means your battery is fried. In this case good news because you can easily replace it

unfortunately it is absolutely not swollen, its fully flat :\
besides this I put out the battery now and put it back and it is showing only 2% percent of battery so maybe my battery is wrong
UPDATE: after uninstalling the pro version of Battery Indicator there were no random shutdowns at all, but the free version is fine o.0

Reboots every 2 minutes: external supply did not help

Guys,
I just bought a Note from a guy who only mentionned that after boot, he could enter his gmail and samsung credentials and then was having a error message : "shell cannot read videos"... I thought this was simple to fix by re-installing JB. The price was attracting because of this issue that the guy could not fix himself.
OK, I knew this was risky : when I received the phone (yes I did not see it before I bought it !), I did not get this error message at all..., but I noticed that the phone was rebooting every 10 minutes when fully charged, and every 2 minutes when batttery reached about 20%.
When fully charged, I could use Odin and install 4.1.2 (XEU-N7000XXLT9-20130611091825.tar.md5) with secured kernel (almost stock) fron philz (PhilZ-cwm6-XXLT9-ORA-5.08.5-signed.zip). This did not fix anything.
The phone is 3 to 4 years old, so is the battery as far as I know. So I first guessed the reboots would probably be due to a weak battery that could not stand the required voltage when the phone was attempting to draw too big a current.
But before I get a new battery, I tried to monitor its voltage during the reboot. I installed to (thin) wires on + and - terminals of the battery connector and connected them to a multimeter while the battery was in place. Unfortunately I could not observe any voltage drop when the phone rebooted. Which tells me it might not be as simple as an old battery problem...
I tried 2 other experiments. The first one was to drive on my 2 wires the same voltage level as the battery from an external supply (I had to keep the battery in place otherwise the phone would not boot, even with a 19kohms resistance between gound and thermistor terminal in the middle). I could observe up to about 300mA drawn at boot time, then around 150mA when ON. I was hoping that the phone would not reboot by itself anymore, as my external supply was not current limited (it could drive up to 1.5A). But it did...
The second experiment was the same, but with an additional (big !) 200nF capacitor between supply and ground to filter out any voltage glitch that could not be captured by the multimeter. The phone lasted longer, but rebooted after about 10 to 15 minutes
What do you guys think ? Do you still think a new battery would fix this (I doubt) ? Do you think I should try another android version ? Get back to Gingerbread maybe (I would rather avoid ICS as I read that ICS could brick my phone due to unsecure kernel...).
I noticed I could accelerate the reboot when trying to listen an mp3. At that time the phone starts lagging as hell, and I get a "bad format" error (the mp3 was the Ringtone.mp3 installed with the OS...). After a minute or so of such lagging , it rebooted. But if I just let the phone ON without starting any app, it still reboots after a while.
Any help, thought, comments appreciated !
Thanks and regards

Does the battery or phone heat up? It sounds like a battery or hardware problem, but you could try using a JellyBean rom first to make sure.

Thanks AutumQueen92, no, it does not heat up. Also I checked, the battery has no bulge at all (tried to make it spin on the table).
As I said, I installed JB 4.1.2 (XEU-N7000XXLT9-20130611091825.tar.md5), actually the first thing I did

Guys, I finally decided to try a step back to Gingerbread. It was very hard to get ROM links that were not obsolete. But I finally found some from here (in french)
I was surprised that I had to use a PIT file... which I did as mentionned. It almost bricked my device ! It failed. I then restarted the phone and got a message that an update had failed and that I should go to recovery and connect to Kies... I then tried to flash back 4.1.2 from Odin, same : FAIL... I then tried to reflash the PIT alone : FAIL ! Wow that was hot. I finally tried to reflash the whole GB + PIT and it worked fine this time
And you know what ? It's been running for 2 hours with no reboot !
Now I haven't told everything about the problems I am having with this phone : it does not have any sound... No sound from the louad speaker, no sound from the jack. Actually I had not noticed it until after I had opened it and teared apart... But I'm pretty sure the sound did not work right when I got it because I never heard the keyboard making any sound while this is the default setting after installing a new ROM.
I also have no Mic... I have not tested a phone call yet though (I have no big SIM card anymore), but google search voice recognition tells me the mic is not available. Gingerbread did not help on this.
No Mic and no speaker could be explained by the little daughter board that handles both. This costs 19€ on internet... But this would not explain that there is no sound on the earpiece either... My theory is that my audio chip is dead and that some checks implemented in JB make the phone reboot, these checks might not be implemented in GB... This makes me think that I might try going back to JB and see if it would still reboot if I'd turn all sounds off...
Any comments are welcome !
