Improved my battery life after leaked OTA

I thought I was losing my mind, after installing the OTA, I modified my qwerty.kl file to wake up the phone from the optical button. I noticed that my battery life was lousy, and originally thought it was because the OTA was buggy.
I restored the stock qwerty file, and no more wake-up from the optical button. My battery life improved drastically.
I heard that this change could prevent the phone from sleeping, thus the crappy battery life. Is this true?
Hope this tip helps.

Re
Anybody else have a faster draining battery because of the optical wake fix?

Could be just because you are accidentally hitting the optical trackball while its in your pocket or somewhere else? I use it on PMF's 2.2 ROM and haven't noticed any additional battery drain.

I think its because we are all forgetting to clear battery stats. It is even required on my rom, jdfroyo

What exactly does clearing the battery stats do? Do you think it would help me? If my phone completely dies or gets down to the low battery warning, the phone doesn't want to charge at all.
It says it is charging but the battery icon isn't animating and the charging led blinks repeatedly instead of staying lit up. Even if I shut the phone off the led still blinks while it's plugged in the charger.
I have to do several reboots and battery pulls to finally get the phone to start charging.
Didn't have any trouble until I applied the OTA and flashed a 2.2 rom.

this is very intriguing. i'll check my battery against my fiance's when she gets home and report. i did the optical_wake script on mine and not hers. i'm pretty sure she had 40% when going to bed last night and I was changing out my battery for my backup. i chalked it up to streaming the race for 30 minutes while we were out shopping, but I think the optical_wake script might make more sense.
PS. both have 1500mah HTC battery ordered from bidallies on ebay for $15 =).

No difference. Our batteries were within 5%. I guess flash vids are pretty taxing on our batteries.

Interesting....maybe I'm just losing my mind and imagining things?
Thanks for your update - after I install the new OTA leak right now, I'll see how my battery life is with the optical wake fix.

Check out jdfroyo when i update it. I tweaked it so you get 15-35 min more battery and no overheating!

Myself as well as many others would be interested to know what this tweak is to achieve better battery life.
Some of us out there actually like Sense - from what I understand, your ROM is de-sensitized?
Any chance you'll fill us in as far as what tweaks you've made? I'm sure I'm not the only one that would thank you.

Phone battery drains quickly

Recently I've noticed my phone dropping percentages within minutes, I've been on my phone for about 30 min just moderately surfing the web and it has dropped almost 30 percent. I tried juice defender, although it seemed it
worked somewhat it was really messing with my data connection. Anyone else experiencing this issue?

As of right now I'm just rooted with the update.zip, I did lag fix but unlag fixed shortly after. Didn't have this problem when I was stock battery actually listed a good amount time.

There are bugs with the displayed battery % not being accurate. Especially if you power down the phone while it's charging.

My Vibrant just eats battery by the minute... I am honestly not sure what is going on. IT's 2.30pm and I barely used the phone and it's down to 53% now from 9am.
What can I do to fix this? I have rooted and installed lag fix from this link

I had the same issue before applying ryanza one click lash fix. My battery now lasts aboutlag 2 days. Which lag fix did you apply ?

I know this doesn't help... but my phone is stock and with normal battery management practices I'm not having any real problems... However, I'm really used to my blackberry which could be left on forever without using any battery at all.

Yea compared to my last two smartphones, the vibrant battery life is no worse. It's definitely better than the n900. But no smart phone's battery life has compared to my blackberry's I used to use.

Fix permissions via recovery! Drain your battery till power down and recharge it fully while off if possible.
Vibe the XDApp

I had this issue. Turns out my battery had swollen due to over heating. Excessive use while on the charger. In the end, it would take 7 hours to charge 80%. Hence why it was on the charger.
Doesn't sound like you have the same issue. But of you start experiencing charging issue coupled with rapid draining get the barry replaced. No issues anymore.

Yep, I can say it TRULY sucks. Dual core processor and 4g doesn't help though. Also motoblur I think constantly syncs your facebook crap when you don't know it.

Been there and fixed it on my device. Check the battery usage stats. If there is a motorola.services process using the most battery, it is likely one of your sync accounts causing the drain. Does it get really warm when you are not using it?

If we get unlocked bootloader will we beable to take off motoblur and put better stuff on

did you flash with 100% battery? sometimes a flash will mess with the battery stats on android, you may be down to 50% but that doesnt mean thats what you have left. let it calibrate with a few charge cycles and check if you have a program constantly syncing in the background.

Yeah, too bad you have to mod the device to get better battery life. Atrix battery life is amazing.
OP, if you're at 50% at two hours, you're probably playing heavy games with a live wallpaper running and your phone min/maxed in SetCPU. I've gotten two days without a charge on a stock Atrix. My Cm7 Inspire still has worse battery life.

My phone was actually just reflashed and i was in church for an hour and it was already at 60 came home made a couple of calls and i had 50% .... my sister has inspire and hers lasts longer then mine!

I get around 38 hours on my Inspire, but only with light use.
But still, that sucks compared to what I got on my Vibrant (around 50+ hours)

Inspire ftw!

I have the Bell Atrix version. Hopefully Bell gets the same battery upgrade as the AT&T users recently had received. I could probably use that extra 10-15%. With that said even in its current state, this phone is still waaay better than my HTC phones in terms of battery life.
If HTC could give us better battery, I'd probably go all HTC. Unfortunately battery means more to me than mods...

Nexus S battery

Hi did anyone experiance this kind of battery consumption? 3days 14hours and 45min and still have like 7%?

Not personally, I use my phone too much to get that kind of life out of it. Based on what I know about the drain when it's screen off and sleeping, though, I think it's well within the realm of possibility with light use.

I get like 24 hours out of mine... with some light-moderate use... used to be better when I bought it but then after installing some apps it just starts degrading a bit I guess

Well, rechargable batteries do degrade over time, and the more apps you have on a device, generally the less time it will last on battery, partially because those that run in the background consume more system resources and partially because those that update data in the background will keep your phone "awake" more of the time.

If I wasn't using my phone and just let it idle (sync on, airplane mode off) I'd get like 12 days of battery life. That's what I like about the NxS, unlike other smartphones it does actually last longer when not used.

hi
i am getting around 10 to 12 hours. wifi always on. mostly watching youtube videos. netbrwosing. gaming.
2g phone calling
still i think i am getting reasonably good back up

Disabling wifi,gps,bluetooth and reducing screen brightness will improve battery life.

That's no issue, but working as intended.
Other phones are using the same technique, but they are hiding it by showing the 100% the phone never reached, that's why they drop to 95-97%ish right after unplugging and from there drain normally.

I experienced battery drowning after using app's like maps or latitude. I had to kill them manually, now I'm cleaning the phones memory regularly. That safes a lot of battery life for me on the one hand, but on the other hand loading app's isn't as fast as before.
It's the classical trade-off between battery life an usability. And 10-12 hours are normal for me if I'm using my phone a lot.

Well, depends on the manuf. if they want to "hide" it or not, they could also set 95% capacity as "100%" displayed. All batteries got a safety feature of some kind

Have you ever dropped your phone in water at all? Maybe you have a bad battery, because those battery stats are worse than even running complete stock. Post all of your info, Hboot, radio, kernel, etc. And hopefully we can help you out with your issue.

Hboot: .92
Kernel: Tinys gingersense 11/19
Radio : 2.15.00.0808
And no never dropped it in water
Sent from my HTC Droid Incredible using xda premium

that sounds unreasonably bad. I'm on Joelz Prime, too, but I think only up to R40. I doubt there's anything in those last few commits to cause this, though. Try re-flashing, wiping battery stats, and give it a few cycles then reevaluate things. What apps are shown in the "Battery Use" settings menu?
Failing that, could be some hardware issue causing a short or something that's draining things... There have been cases where water or other damage can kill the battery life. Good luck.

I reflashed 3 times and still horrible battery life .
Water never got on my phone .
And in battery use nothing major is running . Except like display, os ect.

I've been using Joelz XL 4.0r42 for a few days now and I can say battery life is a little worse than 3.9, but not down to 3 hours. I change overnight, disconnect at 7:30am and charge again at 11pm. But that is with 5 or less calls, 10 texts, and emailing only.
Could email be on push? Did you try the power settings under tweak? I have tried normal and performance and see no difference. Someone said that one of the widgets was killing performance in an earlier post (in the PrimeXL thread), maybe the same widget is killing the battery too?

I dunno, then... try leaving it in Airplane mode for a little while, to see if it's something radio, etc.-related. otherwise, something's probably wrong with a hardware element somewhere along the line. I hope you're able to solve the issue.

I've read a tip to do this:
-get battery full before installing ROM
-wipe battery stats and flash new ROM
-Let it settle in, set it up a bit, then fill up the battery again
-go back to Recovery and wipe stats again, while it's full.
I'm not clear on the logic behind it - could be somebody's superstitions - but it's not a difficult step to take in the hopes that it does some good.
there are others who said they run a script at shut down to wipe them every time the phone reboots. Seems like everyone has their little tricks.

This may be a long shot, but my guess would be some kind of internal hardware issue. Maybe there's a problem with the micro USB port and it's not actually fully charging the batteries.

Shut the phone off and charge it till the lights green. And if you want any kind of battery life, sense is not the rom to be on. Especially 3.5.

Sent from my HTC Droid Incredible using xda premium

There are tons of things that effect battery life and tons of things to save battery. Underclocking, undervolting, lengthning time between syncs, increasing wifi scan interval, lowering screen brightness, keeping running services to a minimum. However even with your phone set to max performance settings with all the bells and whistles on, you should still get more than 3 hours out of a charge. If multipul batteries give the same results, i would say its hardware related, or your charger is messed up and its not charging or messing up the batteries.

I wiped battery stats andseeing where that leads me
Right now when I wiped it and I played modern combat 2 for an hour and my percent is 61
So ill say imma get 2 hours out of my batt?
