My battery is acting up on me I charge my phone to 100 percent turn it off then I will go to bed and wake up turn my phone on and it says its only 50 percent charged so I have to charge it again. I calibrated with an app of the market followed instuctions to the t months ago thought the battery needed time to gets its memory again but its been long enough.
First, how old is this battery? If you've had the OG Droid for a while or bought a used Droid, try grabbing a new battery on the cheap - try Amazon.com. A new $5 battery was far better than my 1-year old piece of junk battery.
Next, are you running a stock image or did you root your phone? Rooting and installing a custom rom - I highly recommend Steel Droid - really helped my battery life, but that's only if you want to take the risks involved. You can also reset the battery log if you root your phone and install Rom Manager.
Its probably an app like droid tv keeping your phone awake. I had droid tv on my phone and it would drain a fully charged battery overnight

Thanks for the input. My phone is rooted and Im running the chevy rom simply stunning 5.2 and loving it. I did some research on this board and found out a good way of calibrating my phone instead of the app I got off the market. So far its working great. But I do need to get on amazon and buy a new battery.
How do you guys save battery on your lg revolution? I have LTE switch to turn on only 3g to save battery but what are your guys tips for saving battery?
I use JuiceDefender.

My battery lasts 8-12 hours depending on how bad I beat on it.
My active days, I listen to music, play suduko, check xda, play in the market. Listen to tune in radio.
That said. I don't know if that is short. I think it's pretty long, and am happy with it. I have the decrapified rom, love it. I have App Killer by Rechild set on a widget. So I go in set what I want it to regularly kill, and tap the widget through out the day. It's mostly my android process that hogs the battery according to widgetsoid.

does juicedefender help a lot?
12 hours seems like a long day and good amount of hours. i hear task killers are bad for your phone though
I was averaging 9-12 hours with decrapified 1.1 depending on use. JuiceDefender extended that another 1-2 hours but added 4-6 seconds before I get 4G back when the device "wakes up". It turns the radio off and I have it set to ping instead of constantly syncing. 3G comes on 1st, then 4G...

Sounds ridiculous but i turn airplane mode on when i'm not using the phone. Turn it off every couple hrs to see if i got any emails or texts or something. Huge battery savings. I have the accurate battery mod posted in the dev forum so if i wake it up after sitting for an hr it's down 5% if i leave airplane mode off, but if i turn it on, it's down like 1%... maybe.
Once cm7 is available, we will see huge battery improvements, i have no doubt. Gingerbread is much better w/ the battery than Froyo. I saw huge improvements between cm6 and cm7 nightlies on my droid, to the tune of 200% standby improvements. Still heavy use i wouldn't expect more than 15 hrs, but imo 10 hrs is ridiculous. There's not really a huge difference between heavy and light use in battery time either.

good to know! thanks. when is cm7 available for the revo?
Thecubed is currently working on it.
Buy an extra battery and wall charger off eBay... Throw the battery in your back pocket, and you're set all day. I swap the battery out after about 8 hours (when I get to about 20% battery) and I'm good the rest of the day. I've had to do this with EVERY Android phone I've purchased. The OG Droid would only get me about 10 hours right when I got it, but Undervoltage Kernels, and decent Rom's brought it up to around 16 hours on the standard battery. The Samsung Fascinate was horrible - Roughly 6-7 hours out of the box. Rom's got it up to around 12. The Droid Pro - 8 hours at most on the standard battery, never saw any improvements with my usage. Droid 2 - 10 hours out of the box, but when CM7 came out on it, I was averaging around 16 hours before I got the Revo. The 8 hour battery life didn't surprise me. I kinda expected it, and had already placed my battery/charger order before I went and got the phone. I'm not a fan of extended batteries just because of the extra bulk, plus finding a case w/an extended battery is a PITA. And the 3 minute downtime from a battery swap really isn't that bad (especially if you've ever had a Blackberry).

good information. but i don't feel safe buying one off of ebay because i don't think the volts will match and it will have bad results on the phone. i can't find a cheap yet any case for the extended battery. i'm sure CM7 on the revo will help the battery a lot. we just have to wait now...

Agreed, I don't buy from overseas with the battery but the charger really doesn't matter. I got a genuine LG battery for $19 and then just a generic charger for it for $8. Knock on wood I haven't had any problems with the chargers I've gotten, but I don't trust generic batteries either.

verizon has for 50% off so is $25 including back cover had a extended batter for droid 1 makes battery issue go away can use alot more without recharge
Up to 20 hours normal use til completely dead battery , on standard battery.
I'm fine.
wow
wish i got on 4g or 3g all day?
stock rom ?
just curious i am lucky to get 8 hour shift and down to 30 %
on 4g and custom rom also
Unleashed, unl3ashed. how ever you spell it. 1.4
Normal use for me tho, is the phone sitting idle in my pocket a lot cause of class and what not.
I'll send out probably between 100-200 texts, talk for 10-15 total minutes, maybe do a web search or two.
Battery profile set to turn data off after 15 minutes of inactivity, background data off. Screen brightness all the way down.
Like I said before in another thread, you could turn CPU scaling to ondemand and that, from my experience, saves a little juice, but has random restarts. You could also try leaving it on the stock mot_hotplug, and turn the max freq down and see if that helps.
I'm on 4g half the day, 3g the other half (when the radio is on of coarse).
Gotta recalibrate the battery too if you haven't done that. I've done both the app, and the manual way in CWM, both work fine, per long as you do it with the phone at 100% plugged in, and let it completely die before you charge it again.
What do you mean recalibrate the battery? I didn't think I had to do anything with it???
under battery on market will see battery calibrate

gotta be rooted, thats the fine print per say.
If you can't calibrate it yourself, best to just let the thing die, charge it to 100%, and let it die again.
Still, if that's still what they're going for at Verizon, it's really hard to beat that price-point. I got one and I love it. Over 24 hours on stock with my usage.

**Just an update** 16 hours and 30 min so far with 40% still remaining. Definitely not bad at all and so much better then stock battery. (Was getting Max of 10%/hr with stock) **moderate use including a couple You-tube vids, checking corp mail and gmail, browsing the web, texting, and reading XDA!

Have to have the extended battery. half off doesn't hurt either.
i dont know how you guys get 20 hours on standard battery? do you mean to have 20hours of ideal time?
I picked up the extended battery at launch and love it. I was planning on running the regular battery on the weekends but find I like the feel of the extended case in my hand. With the original for some reason it feels like the phone is going to slip out of my fingers.
Brower facebook and tapatalk for about 20 minutes nothing else. Dropped 8% . I also killed my battery yesterday watching a movie and playing a game took a total of 3 hours. What do you guys think.

let your battery cycle a few times, this phone rivals my iphone 5's battery life, pretty amazing never had a phone before that did that.
No, if it dies that fast then it's user error.
Install betterbatterystats and look for wakelocks.

There's no need to cycle with li-ion or li-po batteries. In fact it's explicitly bad for your battery to run it down to 0.

Running your battery from 100% to 0% is useful in recalibrating the battery in the event of cell mismatches, which can happen over time.

Here's a very good post for information about li-ion / lithium polymer batteries:
http://forum.xda-developers.com/showpost.php?p=40596097&postcount=3
You generally shouldn't need to recalibrate the battery on a new phone (since it's a new battery), but it doesn't hurt if you think your battery may be mis-calibrated. (for example, your phone sits at 0% battery for long amounts of time) Do you have any apps that monitor wakelocks on your phone?
i was complaining my battery was crap yesterday. iv gained 1 hour in battery since yesterday.
GSam reported 9hours 24mins avg battery yesterday. I cycled it once since then and today its showing 10 hours 38mins avg.
Hoping for further improvements.
The phone needs to know where empty and full battery is. I've always calibrated mine by fully charging and killing at least twice with every phone I've owned and had no il effects and got much better battery life afterwards.
So do I calibrate or cycle? If so, how do I do that? Im fully stock and the only battery app I have is the battery guru made for snapdragon devices. Idk if that's what's killing my battery.

It does no harm to run the battery to 0% occasionally, but the advice i have seen is to try to not run li-ion / li-po batteries below 10% too often as that can shorten their life.
For a new device i would run it down to around 10% with normal use, then give it a real long charge till it indicates fully charged, then unplug it and wait a minute or so then plug it back in and leave it on charge another couple of hours to make sure it is fully 100% charged.
After you have done this whole procedure maybe 3 times, you should have a properley conditioned battery. My HTC One is usually at 50% or better after a 12 hour working day, so i am more than happy with the battery life.

You are totally wrong I am afraid. LiON and LiPO batteries do not have memories and neither like a complete discharge/recharge cycle. The rule is 'a little and often' as far as charging is concerned.
Here is a link to an article which will explain further http ://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

They do NOT have memory effect like nickel-based batteries, but they CAN suffer from cell mismatches which require re-calibration (aka fully charging, discharging, and recharging).

exactly!
Basically just use your phone for about a week, then you can start fixing it
My experience and questions
Thanks for this excellent post! I got my new HTC One day before yesterday and like the Vincent's post says, the phone had about 40-50% of charge when it came in the box. I was very excited to see the phone that I totally forgot about recalibration of the battery
I used the phone out of the box, and I have charged from 2 nights (from about 15% to 100% charge) and haven't run the battery the battery down to 0% yet (when I say 0% what I mean is the level of charge when the phone automatically turns itself off to protect from complete discharge). My questions below:
1) What should I do now to accurately calibrate my battery life? When I called HTC customer service today they asked me to do battery reset (steps below).
- Untick the quick boot under settings -> power
- Turn off the phone
- Hold down the volume up, volume down and the power button continuously for 1 minute (the phone seem to boot up and shut down 3-4 times during this process)
- Run your battery all the way down to 0% and then charge it fully to 100%
This seems to be a fair procedure but since it was told by customer service, I'm a bit skeptical. So I would very much love to hear some opinion of battery gurus here
2) Does the 2 night charging that I did affect my battery capacity (has the dent been made already)?
Please let me know, and thanks in advance!
PS. The battery life in my experience in the past 2 days has been decent (I have about 20% from 7am - 9pm) and I'm a moderate-heavy user!
Hi
I bought the Motorola Razr I yesterday, I been using it all day today.
But the battery is abnormally short. It drops very fast min 10% per hour to 27% per hour. I don't think this is normal for a new phone. The battery temperature is 38°c on normal use.
Am I using the phone wrong or did I get a faulty phone?.
I have nfc on all the time until 23% but after that I turned off nfc to see if that was the problem but it didn't seem to be.
I can get screen captures if needed.

you need some circles from full to down then you will se the real power.
but the battery with stock rom is not so great as with the custom rom from omar or max.
i dont think your battery is faulty give it some tryes!
and at least you csn not easy change the battery by yourself

You might wanna figure out what is actually draining your battery. Search XDA for 'better battery stats' and install it. When your phone is not beeing used it should stay in deep sleep for most of the time, if not, check wakelocks to see whats keeping it from sleeping. For me it was mostly Google Now which caused the drain.
ok so the more i use the battery the better results i may get?
One of the reasons i bought this phone was because of the review on battery life e.g. http://www.techradar.com/reviews/phones/mobile-phones/motorola-razr-i-1098183/review/9
Now i have done a wipe of cache and data, did a factory reset. Charged from 10% to 100%. Getting the last few % is hard, this morning i woke up and it was still 99%. Went back after 1 hour to check it was 99% and dropped to 98% while the phone is off and charging.
Once its 100% again i will install the better battery stats as 696 suggested and post my results.
In my pretty long android experience this happens all the time with new phones, after updates.. You can do anything you want (cleaning cache, restart, etc), but it gets finally better by itself after a couple of days.
Don't ask me why, but it works like that.
Battery life of Razr i is excellent, best of all phones (incl iphones) I ever had!
Good luck and have some patience - so simple is that!
Recommended is to charge the new Phone full, before you turn it on the first time. A lil bit patience is needed, but that should help to avoid stuff like this.
And as the Guy above already posted, the battery will calibrate during daily use. It's the same, when you flash or update an Rom. You'll see the "real battery drain" first after a couple of Charges. And don't wipe battery stats in CWM, that's useless.

Did you manage to get to the bottom of the question?
I bought my Razr i 3 weeks ago, I had high expectations about the battery, but the battery only lasts about one day and half, is this normal? I am not a heavy user.
