Battery indicator totally inaccurate, anyone else with this problem? - Nexus One Q&A, Help & Troubleshooting

My battery indicator (in status bar) likes to stick at 80% for a good portion of the day, even when the "about" menu's battery charge indicator states 50-70%. And when the battery is below 30%, the indicator shows 50%. Does anyone else have this issue?
I've tried searching to see if it's a common problem, but I haven't been able to find others with the same issue.

Yes I have the same issue, but I used to have this issue on my HTC HERO too and it was usually fixed by going to recovery menu and wiping battery stats.
So how it works is let your battery drain to about 10% and then go to recovery menu, then wipe, then wipe battery stats. Turn off your phone and put it on charge, and dont turn your phone on again until the red light for charge turns green indicating full battery. That should fix the inaccurate battery display.
I havent done it yet because I just bought my Nexus one a couple days ago and I plan on doing it tonight. Will tell you if it works (it should and does work)
The reason it happens is because as you flash different ROMS on the phone the charge on the phone is not 100 but as the ROM is flashed it makes the current level as 100 and messes up the display. Also you should never start your phone with the charger plugged in that messes up the battery levels too.

Can we wipe the battery info without rooting? How do you get to recovery mode again, power button plus volume down key while booting?

You need root to wipe battery stats, and root is very very useful even if you dont apply different ROMS especially because you can use AUTOKILLER.
ummmm...power button and volume down key gets you to fastboot then you scroll down to "RECOVERY" using volume keys then while RECOVERY is selected press power key and your in RECOVERY MENU. I should mention your phone must be fully rooted and flashed with Amon_RA's recovery menu.
If your phone isnt rooted follow this :http://forum.xda-developers.com/showthread.php?t=618768

[Q] Battery discharges when off and slow boot

Hi all,
Just rooted by Nook Color with CM7 and I 2 fairly major problems. I searched threads but could not find anything specific to my specific problems.
First, last night, I turned off the Nook Color by holding down the button on the left and selected "Power Off". When I booted it (after a long wait, see below), it booted but the battery was very low and I checked the battery life settings using Spare Parts app and it said it had been Running 100% of the time since last unplugged. Its as if it didn't power off when I asked it to.
Second, my reboots are super slow....I get the "Read Forever" words when I hold down the left button but it takes several minutes before I have to press the bottom button to get the screen (no indication that its booting or anything).
Any help would be greatly appreciated.
Why are you shutting it down at all? Just let it sleep. Even with the current sleep issues, it will only use 1% or so of the battery that way... try it. I hardly ever power off my nook. As for the slow boot time, there are a lot of reasons...
1. Did you install the OC kernel and forget to wipe dalvik cache?
2. Which version of CM7 are you running? a nightly, or the 7.0 release?
I just did a test.
CM7 cm_encore_full-63
update-CM7-dalingrin-OC-emmc-040411 set at ONDEMAND 300-1100
At 2am battery was at 100%
Standby for 9.5 hrs and it consumed 16% battery.
Not looking good to leave in standby.
Do you leave wifi on? It could be syncing or trying to sync the whole time it is on standby.

If you powered off your NC, it would not be using battery.. Period. Running 100% of the time is normal right now on CM7, but again, it was not running while it was powered off.
Slow boot? Are you using an SD card? If so, get a new one that's faster.

[Q] (Q) phone battery life poor after update

hello guys

How?
The phone is not new. Been no this Rom for about a week
I used this quide and all OK...
After the update:
In recovery mode, select options Wipe data/factory reset and also you need to select Wipe Cache partition and also you need to select the option of “Clear Dalvik Cache” after which you need to reboot your device by selecting reboot system now after which all the cache files will get deleted.
You already tried calibrating the battery? And when you install a new ROM you generally have to wait a few days for the battery reaches its normal duration.
the best battery life i have ever had was on MIUI. It was like two days ... no problem. i heard for some guys it was even up to four days.
you are on a gingerbread bootloader, so its no problem to flash MIUI with a *.zip file in recovery. just search the forum here for a good version.
to do:
-glitch kernel
-download a governor ("conservative" or "ondemand")
-two apps from the market: CPU tuner, CPU spy
-search for tutorials for CPU tuner
=> fixed your problems
if you have flashed yout rom with your battery not fully charged, you have to calibrate your battery
And also doing 3-4 full charge
yes, u need to do full discharge recharge cycles 2-3 times... wipe battery stats after that from recovery mode on full 100% charge.
Hope this helps
I have two phones. Both running same Rom but i only use one phone. The other i charge the battery in
only just had to do that since the update.
So the batterys are always fully discharged and recharge.
I didn't know about calibrating the battery ill look into that now.
Thanks for the advice.
Just calibrated the battery fingers crossed this work. Half a day for a phone to last is poor.
Was thinking this is like the iphone
when you guys have fully charged your phones and you go into better status how many how's does it say it has left.
Is it random?
Mine says 40 hours
edit lol now it says 7 mins 40 seconds but battery is still full

You still didn´t gave the time battery needs to settle down. In a couple of days you will see that battery will again last for 2 days easly.
For a better rom that you ask on the first post find it on i9000 development forum. There you have roms with different specs. Choose and test them for yourself and see wich fits you best.
I should say for you to test the Hybrid.

Turning off most app synchronizing (settings » account & synchronisation settings) is making a big difference as well, at least to me. Just disable automatic synchronisation (keep background synchronisation on), and turn it off for all apps. Saves me quite some hours of battery. I'm assuming the update reset all your synchronisation to ON. I'm never using the word synchronisation again, pfft.
hello koooowweeee
Try BatteryCalibration (market) or.
1. Connect the charger to the phone while it is on, and let the load be up to 100%.
2. Unplug the charger and turn off the phone.
3. Reconnect the charger while the phone is off, and leave the task until it shows 100% again.
4. Unplug the charger, then turn the phone, wait for it to boot completely, then turn it off
5. Reconnect the phone to the charger (always off) and wait until it returns to 100%.
6. Disconnect the charger, turn on the phone with flight-+ power to access the Recovery.
Once in recovery, go to Advanced, and make a Wipe Battery Stats, then reboot the phone.
or flash CM7 7.0.2 Kang!
@ +
Well been using my phone all day and battery has lasted so far. Its on 13% now which is better than it was
ill try the method above tomorrow morning and see if that's better
the guide i seen on here was to charge battery to 100% then take the charger out and battery for 90 seconds then put it back in.
Seems to have worked

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.
Your battery is dead.. Buy a new battery

have you tried calibrating your battery? if you haven't try this.. i always do this when my battery gets miscalibrated. 1st turn off your phone, take out the battery and leave it for 1 to 2 minutes, put the battery back, go to recovery mode and to CWM recovery go to advanced and wipe battery stats, reboot your phone
give feedback if it works or not,,
This doesnt calibrate the battery,it only delete the logfile of the battery.i think he need a new one.please op,next time ask in right section.
MANY GREEEEEETZ!!!
Use only 2G Networks
1. Proper way to calibrate battery:
Drain the battery completely (use an Xposed module called disable critical battery shutdown, google it). Then, recharge the battery to 100% (DON'T unplug the charger cable while charging) and done.
2. Underclock when necessary.
3. Don't run too many apps at one time.
4. Make sure that deepsleep is working.

1. You can use Wakelock Detector from Play Store.
2. It is normal behavior...... if the battery status won't move from 99% to 100% after 1-2 hours (while charging), there might be a problem.

Battery of my I9000 acting weired after few flash

Hi, i dont know if i am on the rightt topic but anyway i hope i will get an answer here, my galaxy S after few custom roms installed & reinstalled & with battstat reset few times now after i came back to stock rom 2.3.6 & even before the battery sustain good, but just when i try to play a game or use it on store for while (few minutes) the phone turn off, & when i bk it on it says battery low put in charger despite it is 100% full & after a while it increase & level up to the original status, so my question is, is the phone need calibration or anysort of bug fix or it is hardware problem; thnx cheers
Have you checked the contact points between the phone and the battery, maybe just give them a clean, and yes there's no harm in calibrating the battery, just boot into recovery and wipe battery stats.
(don't charge the battery until the battery turns off your phone)
1. charge the battery FULLY
2. boot device to CWM Recovery
3. advanced/Wipe Battery Stats
4. reboot device
