Using an extended battery

Hi
Got an extended battery for my G1 a few days ago from ebay.
The problem is, the phone doesn't recognized it after I switched the battery. I had the same charging % as the previuos battery right after I changed it (even though I never charged it) and the max use time in Battery time lite is the same....
Any ideas ?
Thanks,
Nati

bad phone ? my ext batterys work fine from ebay

is there any way I can be sure ?
Maybe it a firmware thing ?

I had similar issues when I first got an extended battery (Seidio 2600mA). After performing the steps below, I had no problems at all. I hope it works for you.
Try a COMPLETE drain and recharge cycle, a couple times.
Run the battery down until the phone shuts itself off, restart the phone and let it run until it shuts itself off again. Repeat until it will NOT boot anymore. This will take a surprisingly longer time than you think. Load up your music player, youtube via 3G, etc... kill that thing.
Once the batter is so dead that it can't even load the splash screen for a boot charge it up, but do not turn it on. Let it charge up to full for a few hours (usually four will do it) and turn it on. If it's not at 100% yet, let it charge for a while longer. When it's at 100% take it off the charger and run it down again like before. Run it until it is totally dead.
After a couple cycles like this, you shouldn't have any problem with your phone and battery giving accurate charge status results and operating as it should.
I've read, from a few sources, that between the internal monitoring on the battery works, and the way the G1 reads the battery state, that this complete drain and recharge cycling helps to establish baselines for "empty" and "full" and keep them synchronized. If your phone has never seen an extended battery and the battery was at partial charge when inserted, it may not have been able to accurately gauge the minimum and maximum extents and give faulty readings based on prior battery data.
That could be wrong, and I don't know for sure. But, a complete drain and recharge never hurts anyway, and in my case it actually seemed to solve the problem for me.
Good luck!

[Q] YABPT (Yet another battery problem thread)

I have had battery problems plague me for the last month, regardless of flashing, reverting to stock etc.
The following data is compared to my friends captivate, who is running the same setup as I am Continuum 3.11 and Speedmod k13c. He currently gets at least 24 hours on a full charge (thats WITH gaming and calls etc.). I can barely scrape 10 on minimum use.
At first I thought it was a rogue app that was constantly draining, but unfortunately it was not (after several trials and monitoring apps).
Next, i tried reflashing, Master clearing + flash from stock, flash at 100% charge, but still nothing.
Next thing I tried was to see if it was my battery was faulty (doubted it because it was new from original phone. Only had it for 2 months) by swapping batteries with my friends Captivate (also original battery). I concluded that this was not the problem since he was getting great battery life (if not better since mine is newer) and I was still draining.
After, I tried battery stats wiping, recalibration (bump charging) flash to stock and flash to a rom with reportedly good battery, with k13C speedmod. Still bad results.
So heres my current situation: I am running Continuum 3.11 with speedmod k13c. I have tried almost everything in my arsenal and googling but I have come back empty handed. It is NOT the battery, rogue app draining OR rom/kernal. I am completely stumped.
Heres a summary/extra details of my trials:
-Flash to stock and try again
-change batteries
-wipe stats, drain and recharge, charge for 8 hours, bump charge (recalibration), flash from 100%, master clearing etc.
- setting brightness to lowest, wifi off, plane mode when turning back on
- being anal and not installing new apps / using what rom came with
- My phone remains ice cold on standby. I know that when it gets hot, it drains (during standby and etc. but this time its ice cold)
- Here is some data: In one hour of minimal use (checking texts, replying etc.) I lose 10%. overnight I lose around 20%. In a heavy usage, 4 hours.
(note : I know that some of you might consider that barely passable battery life, but if I directly compare to the set up of my friend, its not right since in heavy usage he gets about 12 hours, which is my max per charge on minimal use)
Im hoping someone can help me with this problem, because I believe that this problem is plaguing other peoples phones as well, not just mine.
REFERENCE THREADS THAT I HAVE LOOKED AT:
This one
And this one of course
EDIT:
I recently swapped batteries again with my friend, because I recall fixing it at one point, but I had to reflash it due to a bug or something, i dont remember. But when we swapped batteries and swapped back, I seem to have fixed it. This leads me to believe that My phone right now has no idea where 100% actually is and its only charging to some random % that is NOT 100% .
This time, I swapped with him when he had 47 percent, and I had 87. After we swapped, we immediately checked the percentages. To my surprise, his 47% on my phone immediately turned to 23% But strangely, that 23% remained (the charge on 23 seemed to be holding for quite a while). But when I recharge, it charges WAY too fast (10 minutes of charging = 40% in total from 23%? B.S.!!!)

I guess thats happen when you flash new rom or kernel or modem...you need to wipe battery stats to fix that....

I wish it were that simple =( I already tried that via recovery. Unless the recovery method is bugged and not actually wiping the stats. I will manually delete the battery stats and retry, but I dont think it will work.

im just reporting back that manual battery stats wipe did not work =( Any help please? I am absolutely stumped

sorry to triple post but I thought I should ask something else:
Would extracting the batterystats.bin from another captivate and using that one work? (assuming i set permissions correctly)

[Q] Wifi battery usage after update to Gingerbread

I've been experiencing huge troubles with Wifi battery usage after installing OTA update. This is a huge problem, because I have to always keep charging phone while at home. When using default version 2.2.1, my phone used 2-3% of battery per hour while idling with screen disabled and connected to wifi network. After updating to Gingerbread it consumes 6-7% of battery each hour using the same settings. Battery life with wifi disabled is comparable or even better than with Froyo. There are no power hog apps in battery monitoring and performing factory reset hasn't changed anything.
Does anyone have any ideas how to solve this problem? Thanks.

Hello!
Your issue is weird, my Inc S is performing better in terms of battery consumption with 2.3.3 than the stock ROM...
Have you tried to make a full "fresh" install of the 2.3.3 ROM ? I read somewhere that sometime, OTA updates are messing up with your phone.
Try this ROM : http://api.viglink.com/api/click?format=go&drKey=1359&loc=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D1033922&v=1&libid=1305916498140&out=http%3A%2F%2Fwww.filefactory.com%2Ffile%2Fcb17e37%2Fn%2FRUU_Vivo_Gingerbread_S_HTC_WWE_2.12.405.7_Radio_20.2804.30.085AU_3805.04.03.22_M_release_187295_signed.exe&ref=http%3A%2F%2Fforum.xda-developers.com%2Fforumdisplay.php%3Ff%3D1028&title=%5BROMs%5DIncredible%20S%20Shipped%20ROMs%20Collection%20-%20xda-developers&txt=http%3A%2F%2Fwww.filefactory.com%2Ffile%2Fcb17...295_signed.exe
After flashing, do a battery calibration :
1. Let the phone drain all the battery until it just can't boot anymore; When it turns off by itself, turn it on again and again until it won't start,
2. Take off the battery for at least 1min,
3. Put back the battery, let the phone off, and put it in charge for the night,
4. Once it's fully charged, take off the battery for at least 1min,
5. Put back and turn it on.
Hope this helps!

I am having the same problem....Have you managed to fix it?

BATTERY LIFE (After Upgrading Froyo 2.2 to GB 2.3.4)

I recently upgraded from Froyo 2.2 to Gingerbread 2.3.4 and now the battery life is absolutely terrible.
Before upgrading, I would get at least 2 days of battery on Froyo. Now, on 2.3.4 a 100% charge leaves me with only 40% charge overnight.
I'm not running any background apps, I turn off Wi-Fi/Bluetooth and so on. I also turned on Airplane Mode to disable network connections.When checking the battery information, cell standby used 29% and phone idle used 71%.
I did some research, and some have related the problem to the battery forgetting it's charge level due to the OS upgrade. A solution is to factory reset the phone and run the phone until completely dead, and charge it overnight for 6+ hours or longer (imagining the phone is brand new again).
What are your thoughts on this?

What ROM are you using? ZEUS has great battery life
Sent from my LG-P970 using XDA

V20b, I updated using the LG Software Update Tool.

A system restore would not be necessary if you are rooteded, just a simple battery calibration. You can get the app on Google Play.
It will delete the batterystats.bin file that was created on your Froyo ROM and generate a new one one the Gingerbread ROM.
But then if it has forgotten, the percentage of energy left would be inaccurate thereby showing false results. The stock battery stats function is cr*p so i would suggest using a 3rd party application to monitor battery usage and current.
That would be a better indication of what is eating up your battery.

Found a suitable battery calibration app. However, my device is not rooted. If I do root my device, I lose my existing manufacturers warranty, right? My phone is less than 2 weeks old, contemplating on whether or not I should proceed to do so.

Yes you would lose ur manufactures' warranty although if u were to flash using SmartFlash or KDZU and do a system wipe, your device will be untraceable. They will never know that u rooted and u can just claim that you got advice over the phone to perform a factory reset.
Rooting is definitely worth it. It comes with its perks but also the peace of mind that any errors that you make are reversible via steps above (as long as you don't drop it and break the hardware).
You could try a factory reset if you don't want to root. Just make sure that you are recharged 100% so batterystats.bin will be as correct as possible.

Thanks for the help.
I think I will charge the battery to 100% and perform a factory reset, and hope the battery improves from there.
Will post an update later.

Same Problem
Same here, had awesome battery life on Froyo then updated to Gingerbread (V20A) using the LG updater and my battery life is now terrible. A solution to this problem would be nice. Any easy way to root my phone without having to flash it? Want to put CWM and do a battery swipe.

yes, you can have back your warranty by flashing back stock rom
my advice is to not install battery savers, just install a simple task killer, root the device and install custom roms which have good battery life
i personally use Zeus and the battery is just awesome!
or just calibrate the battery via an app as our friend just said and observe it for some days
(also, factory reset the mobile plz)
then wait for some days as the phone usually calibrates battery after a few re-charges

Update: Battery is back to normal, if not even better!
Test findings: Charged to 100% and left overnight.
13h 57m 50s later, dropped to 93%.
- Phone idle 75%.
- Cell standby 25%.
So about 1% drop every 2 or so hours, about the same as if I was on Froyo 2.2 again.
- Switched off Wi-Fi/Bluetooth/Sync's.
- Switched to 2G instead of 3G.
- Switched on Airplane Mode.
- Used Easy Battery Saver app (Intelligent Power Saving Mode).
Didn't have to root my phone, which means I don't break the warranty. Thanks everyone for the suggestions, especially FunkyGanja.

Yes...as we know the battery calibrates itself after a few recharges
Btw you can flash stock rom and have warranty baack any time

I forgot to mention that I didn't simply just recharge it again, I charged it to 100% and THEN performed a factory reset.
Apparently it has something to do with the "batterystats.bin" file, when I upgraded from Froyo 2.2 to Gingerbread 2.3.4 the battery wasn't fully charged, so GB thought my battery was fully charged at only, say 50% battery, hence why the battery drain so quickly overnight.
I also came across this post, which helped clarify my problem: https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT

Phone switches off saying battery empty when its over 40%!

Hi all,
I will admit I have flashed the phone about 4 times in the past 2 weeks (different roms) due to other issues but now when the battery indicator shows 40% which is rite it shuts the phone down suddenly and says battery empty even though it still shows 40%!!! I can even plug the charger in and it will charge from 40% not 0. It did not used to do this.
This problem has affected 2 (cyanogen & stock LG!) of the 4 roms I have tried now so its not a rom issue and the phone was fully and properly formatted before flashing the new roms.
Even when booting back up it lasts a minute and does the same. Battery drain is not fast and all works fine until it goes below half.
I have wiped catche, battery stats & Dalvik catche many times when 100% charged but makes no difference.
Baseband is correct also.
I really need help as its unusable having 60% of the battery usable.
Anyone got any ideas before I sell it for parts ??
Thanks

do you have problems with battery before you installed anyone ROM?
and maybe isnt problem in ROM maybe battery making problem

Are you using the kernel that comes with each of the roms or are you using a custom kernel such as pengus' kowalski kernel? I know pengus implemented a new battery driver that has been known to cause other people similar problems.
