Hi all,
I once asked why the battery life on my Hero was kinda bad (< 1 day with a full charge), and I did as was described in this post. I downloaded the Battery Calibration App, charged to 100% and pressed "calibrate battery", let it drain the next day , waited for phone to self-shutdown. Then I plugged it into the wall-charger. After a few minutes I switched the phone on again (while still connected to the charger), and immediately after it booted it said it had a battery percentage of 40%. Let it charge to 100%, and immediately when I started using the phone, the percents started to wear down again very quickly (>10% in an hour). Next day I booted into recovery and wiped cache and dalvik cache and battery stats, but battery life still goes down pretty fast. Did something go wrong here? If so, what should I do to prolong the battery life?
When I go to settings -> about phone -> battery, the 2 things I see at the top most of the times are visualizing/screen or wifi. A typical day for phone use for me looks like playing a little game, browsing, using tweetdeck etc at times when I'm bored or texting, so I use it a fair amount of time each day. I just installed JuiceDefender, gonna see that that'll bring me.
I run Elelinux 7.1.0 latest version.
greets,
Danny
i have not used the app yet, but i advice you unistall the app and using root explorer go to the /data/system/ and delete the batterystats.bin file and restart the phone and let it drain down completely and recharge and you should be fine

No matter how long my g tablet is plugged in,
it does not charged until the battery meter says 100%.
It always get charged upto 96%.
Is there anyway to fix this problem?
Is it something that can be fixed by clearing batterystat.bin?
If that so, can I do that using adb? Thank you.
khunny,
This is pretty common with the G-Tablets.
You can run it down all the way and then go into CWM and tell it to reset the battery stats.
But often as not that doesn't change much.
My personal advice (I have one that often does the same) is just ignore it. If it's 96%
you've got no problem and at less than 10% you better be thinking "charge."
Rev
Mine only charges up to 96% as well. Gonna try to reset it in CWM after it drains. Hopefully it works, cuz while having it only go to 96% isn't a huge deal its something I would like t be able to fix.
search is your friend
It is normal. Gtab treats 8.3V as 96%. In theory, 2cell li-ion battery 100% of charge is 8.4V. But, such battery does not like to be overcharged (it will shortened battery life).
mine did charge to 100 percent before installing vegan 5.1 supplement? Now it charges to 98 no matter how long i leave it plugged in? There has to be some way to alter the battyer stats to show 100 percent if it is??
Mine finally got to 100%
I had this tablet only for a week or so. I have installed Vegan 5.1.1. I noticed the battery only charged to 95% or 96%. I have drain the battery all the way, and then "Reset Battery Status" in CWM. But, it did not work the 1st time. Then, I drained it again. After the tablet shuts off automatically, I would push the power button to turn it on a few times to drain it more. Then, I reset the battery status in CWM, AND, I "Fixed File Permissions" right after the battery status reset. Then, reboot the device, and it reached 100%
Note: I drained the battery at work, tried to turned it back on about 3 times after it shuts itself off. After I got home, a few hours later, I turned it back on one more time, and the battery showed 2% and stayed on for quite a while. Not sure why that is. Hope this helps.
Hi all,
I have a question about battery life on the Simply Honey 2.7.2 ROM
My phone is usually idle overnight, but i notice a drop of about 25-30% in 8 hours. Is this usual?
Here are some screenshots
Battery Plot (1.26 am to 9.26am) Battery was 100% at 1.26
System details
Top Apps
Is this pretty normal for overnight battery drain? The Device usage indicates almost no use..so i'm wondering why the battery is draining.
Any help would be appreciated.
Thank you
I'm having the same issue. With Darky's 9.5 the phone easily last a day, now it's lasting 9 hours or so. I just flashed the new ROM yesterday.
This is from the Simply Honey post:
HOW TO RECALIBRATE YOUR BATTERY (by heartagramm):
COMPLETE GUIDE!!!
You'll have to use the phone for about 1-4 days (although it varies depending on the phone and battery used; every phone is an individual). It runs out of battery. Yes. Let it run. Recharge. After 3-4 recharges the battery will "gain" it's performance back.
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%.
And this is the way you should really gain great battery performance.

I'm going to try this and hopefully it works.
Let us know if it sorts itself out after a couple of days...
Chris.
Thanks. I will try this.
I recently downloaded a Battery Calibration App from the market too (NeMa) and calibrated my battery using that..but I'll try this method also.
Let me know if you have any improvements also.
Thanks!

I switched to Doc's ROM and battery life is back to normal. I'll try Simply again after a few versions.

I don't think there are going to be new versions, because he's now doing some Gingerbread based ROMS.
Which one is Doc's ROM?
I'm on SimplyHoneyV1.0XE and have been for a couple of days. This is my first Simply Honey experience but I think this is the best battery life I've ever gotten on ANY ROM including stock. Given it is a little early in my test to determine just how good it is going to be but I would recommend you give it a try and see how it does on your battery.
P.S. My findings were based on the fact that after a 100% charge, light usage (2-4 phones calls, and several texts) for almost 10 hours I still had 89% of my battery. Pretty impressive if you ask me.

I'm pretty sure they perform the same function. When you touch the "Calibrate Battery" button, the app automatically performs all the steps mentioned (wipe battery stats, mainly).
One app you might try is Juice Defender. I've used it a few times, and it worked well when battery life was an issue for me (I've switched to Axura, and it isn't anymore. Neither with Bionix).
The phone was freshly charged overnight. I was using the internet while listening to music through (3rd party) headset and since the 3G signal in the building was kinda ****ty I switched the phone to EDGE (GSM only). Then I quit the Settings menu and opened Firefox, tried to load a web page and at this point the phone froze. I'm not sure if I restarted it or it restarted on itself but after the boot the battery was showing about 40% less. So I turned the phone off, pulled the battery, rebooted, same reading.
I used the phone for a while after that and now it's showing critically low battery and I'm wondering what should I do now?
Is it really so low on battery or the reading is wrong?
Can 40% battery disappear just like that and what could cause it?
Should I charge the battery or let it discharge until it turns off by itself?
Battery screenshot attached.
Perhaps a battery calibration issue caused due to the crash, my advice would be to drain the battery all the way down to zero and let the phone turn off, remove and reinsert battery and proceed to charge till full and then turn the phone on again. Hopefully issue should be a one-off and now resolved.

happend to me before on my htc desire hd..battery pulled and battery stats dropped down the gutter..just let the battery die and charge fully or even just charge it up to 100% from where u at now..doesnt matter it will fix itself...
My phone was doing the same thing, it was rebooting or shutting down two or three times a day, usually a few minutes after taking off of charge.
I have sent it back for a replacement.
Do not drain the battery to zero. There is not reason to go belox 10% charge, as you could damage the battery if going to 0. These are new batteries much smarter then old ones.
You don't need to drain to zero but it won't do any harm if you do. Probably a wee softwre glitch. Wouldn't get too worried about it.
a good option is battery doctor - its a free aplication from the market...
let your battery go down to 20% and then open the app in charging mode...let it charge(dont close the app during the charging process, just keep it open)...woallla.. u have made a full cycle charge - easy as that...
Im a little fed up. Ive had the phone for over a year, and the batteries always been the worst, but lately its been even worse. I left the house at like 7:15am this morning and its 1:45 and the phone just died, and all ive done is text and have a 30 min phone call.
I hoping a couple of you can tell me what youve done to get some more life out of your battery. Ive been running CM7. Ive used Glitch kernel with it before, but didnt see any improvement at all, though i dont know what i was doing.
please help me.
When I was using CM7 my battery was terrible until I switched back to a froyo rom. I am running trigger right now and my battery lasts me all day unless I am constantly watching videos. I use my phone all day long though, from surfing the web to talking and texting and listening to my podcasts and it still lasts me all day.
Battery calibration app and an extra battery is my best advice. I bought a wall charger off ebay from hong kong for $1 it also came with 2 spare batteries that I keep charged at 100% and switch out often because I agree about battery life not being as good as one would like on GB.

Just shut your data off when not in use your battery will last all day that way

Ive been having a weird battery issue. my battery gauge will say its at 15% or whatever it says at the time. ill plug it in and like 10 minutes later it will say 100% battery is fully charged. Obviously its not 100%, even when I charge it overnight, when I unplug it itll be stuck at 100% for like 2 hours then all the sudden drop to like 85%. im lucky if my battery lasts 12 hours now , same thing has happened on different roms. Do I need a new battery?

I'd try a different ROM/Kernel, see if that makes any difference (after clearing batterystats in CWM).
If that wouldn't help, I'd say battery is ze dead.

tried differents and kernels, and wiped battery stats guess my battery is done
try "battery calibration" app. it helps me a lot, and keep my phone running longer. i can last almost a day with medium use.
i have also tested with on screen non-stop (wifi + online game that require wifi, brightness roughly around 30%, medium volume, with whatsapp and talkbox in between), in conclusion, i can run for 4hours plus straight with sufficient battery left. i never push it through, i think i can go for 5 hours if i want to.
battery calibration app can be found in play google store
Worst battery life evah!
Im having issue with my battery as well, I plug it in a electric outlet for about an hour last night and when i saw the charge, it was only like 49%!!!!
And today, before my meeting it was like 22%, after an hour of meeting, BOOM! EMPTY BATT! What I only did was surf and checked my calendar!
It charge slow! And its draining fast!
something happened to my battery before last month, when i charge my fone it says 88% then suddenly after few mins 1 or 2 it become fully charge,but when i unplug my charger it comes back to 88% again, i tried some apps like battery calibration and also i'm wiping the battery stats in cwm everytime i flashed a new rom and it helps my battery charge in normal and accurate level...i'm using also cpu spy to checked if my fone is going to a deep sleep. now my battery lasts for 1day 11hrs with light usage. but for heavy usage i've got 40% after 4hrs of continious hd gaming.
