I still have 39% battery after two days! This is really amazing I think. Granted I only had 2 phone calls in that time but I have been texting a lot and playing around with settings.
How long does your battery last and do you have any tips on improving battery life?
I am running CM7.1 with Go Launcher Ex and have the brightness set on very low plus I don't use screen orientation switch either.

What is your screen on time?

I use matr1x kernel wich has the best batterylife for me, but i still have to recharge every day...
Sent from my Google Nexus S using XDA App

I run it completely stock and unrooted, and get about a day with average use. By far the best smart phone I have owned.

Matrix or Trinity seem to give the best battery life.

Sorry I don't know how to find screen on time.
I put my phone on charge after 2 days 22 hours and it was still on 19% but I charged it to be safe because I am expecting a very important phone call.

Calculating data regarding battery stats using morfic TEUV-S22-05102011, you could reach around 80 hours with cell connected but having very little activity.

Same place as that pic but click on display that will have shown display on time

How did u do the screen shot unrooted?
That's still impressive battery life.

For the people on matrix or trinity kernel, how long is your battery lasting you off charger? And how heavy of a user are you? Just curious been messing around trying to get it over a day :/

My battery life!

I'm having a great overall experience with the Inspire 4G w/ CM7. Just wanted to show you guys some screenshots of the battery life I'm getting so far. These shots I took after a day of heavy usage, including a few hours of net browsing, texting, and e-mails.

Hey try using juice defender or current widget to exceed your current battery life. Both control which apps that are eating up your battery. Kills the non needed ones.

i've seen all the complaints about battery life but i must say mine is more than adequate. maybe because for the first 4 days i had the phone, after charging it for 10+hrs, i ran the battery all the way to 0 (til it shutdown), recharged to full, then drained it again.
it was my old habit from my nokia days.
Yeah, to be honest, this is equal to or better than the battery life I was getting with my Captivate. I can tell you with an absolute certainty that the battery did have to "break in" for a short period, after installing CM7.
Sent from my Desire HD using XDA App
Its deff better than captivate, 99% due to the screen. I got over 5 hours screen on time in a 16 hour period the other day with my rom/kernel combo with screen brightness at about 40-50%. That's pretty damn good, way better than the captivate could ever get
On my LG Ally i was lucky to get 6-8 hours with just light use. With the Inspire on cm7 i have gotten around 20ish hours with moderate to high use.
I'm still shocked that i am able to get that much battery life. lol
I'm still breaking my Captivate records. I took my phone off the charger @ 7:00am on Wednesday the 20th. I'm now at 15%.
What roms are you guys running. Im on coredroid 5.4. I get about 20 h with moderate use. I consider it to be pretty good. But no way can I get over like 30 h. I don't like to use juice defender or setcpu. Don't feel like I should use apps that override android os. Especially GB is so will optimized and efficient.
Sent from my Desire HD using XDA Premium App
I'm on CM7 and only wish I could get the battery you guys are talking about. I just went from 93% to 90% in a matter of minutes doing nothing on the phone. It was sitting on my desk!

Does your phone get lonely spending all that time lying silent longing for your swipe?

Not at all. It's my personal and work cell, so I talk, text, surf, and play games what I would consider a moderate amount. I don't use a large overclock. I use the smart ass governor on Leedroid's most recent rom, and my screen brightness at 1/3.
There are days that I can put it tonthe test, but my first charge got me 35 hours with 5 hours awake time.
That's it? I got this a while ago and that's before I did some optimizations... I'm going to see what it can pull this weekend before it hits the 15% warning.
Apparently I can't add images until I get some more posts.

Battery life

I'm currently running das bamf 4.9 I want to know which radio give u good battery life for that rom
Sent from my ADR6400L using XDA App
None of them. BAMF's battery life was so horrible I switched to Liquid Thundersense. Battery life almost doubled.
Battery life is a combination of Radio, Location, ROM, Kernel, Kernel settings, Applications, Use..etc etc...
There is no magic combination. Try things out, monitor the battery consumption, and find out what works best for you.
I am using BAMF without issues after I reset my battery stats.
I was having similar issues to some where I would lose 2% within a half hour of unplugging my Tbolt, and then be down to 10% remaining after 12 hours with light use!
I am rooted, so I don't know if there is a way to do this stock, but I recently did this which has drastically improved battery life to where I am down to only 82% after 6 hours of moderate use (calls, Angry Birds, YouTube).
Fully charge your phone
While still on the charger, I rebooted into recovery and reset/wiped my battery stats
Used the phone heavily to get it almost dead
When the phone auto shuts off near death, I booted into recovery
Leave phone alone to fully die as recovery leaves the screen on and doesn't turn off
After phone dies, fully charge again before use
After doing this, my battery life was greatly improved. Nothing else changed.
I get terrible battery life with Bamf as well. Just rooted about a month ago and have only tried two roms. Bamf and currently tuning Synergy

How is syenery battery life
Sent from my ADR6400L using XDA App
A lot better than stock and Bamf. I'm a pretty heavy user and was only getting maybe 8 hours... Getting around 12 -14 now. Had Pandora going for about 3 hours straight this morning off full charge and still had 70%.

Hey everyone. Here's a screenshot I took of my phones battery use. I was just wondering if this rate of discharge is normal. My screen brightness is always let to the lowest possible, all power saving settings enabled, phone overclocked at 1.6 with ondemand governor. I am using the sensay XE35 v 2.1.0. How could I improve battery life, any help is appreciated. Thanks in advance.

Screens of the battery use screen would be very helpful.
Did u let ur phone battery cycle a couple times?

Thanks for the reply guys, stabro I've had this Rom for about a week now shouldnt the battery be calibrated by now, or does it need a little longer. And matt, isn't that what I uploaded or is there something else that I need to upload
Sent from my HTC Sensation Z710e using XDA App
The screen you were at before you clicked the graph to get what you already posted. It shows a bunch of apps with how much of the battery it's been using.
Oh haha sorry, blacked out for a moment
Here's the shot of that.
I have no idea why it doesn't show actual apps, but I havnt messed with it. I'm assuming its rom related?
Sent from my HTC Sensation Z710e using XDA App
Was your wi-fi on the whole time, and is your cellular service always on even in standby? Changing those can have a large impact. Did you have better battery life on a previous rom? Is it the stock battery, cause if so, the life on it is typically not very good.
I've found in all the Sense roms I have used, display is always right at the top in battery use. I would normally have mine at a set brightness like 45% during the day and 25% at night which would drop display usage a bit. Plus try underclocking instead of your overclocking to 1.6.
That might be because you had plugged it in for a few minutes. It shows the battery usage since the last time it was disconnected.
LBN1 yeah I always keep WiFi on, my phone is always on 2g mode. Before this Rom I was using miui, the battery on that wasn't the best but it would see me get through the day with medium use, and prior to that, ARHD by far best Rom for battery imo. Yeah I still use the stock battery, though I'm thinking about buying another battery.
I've read somewhere, cant remember where lol, that a low signal uses a lot more battery as its constantly searching for a Signal, I think u guys have noticed from screenshots that my house, has very bad reception

Do you use your phone alot? I am gaming alot on the phone during schooltime, and it DRAINS battery (1% per minute almost) And I usually charge my phone when I come home again. And what kernel do you use? I use Bricked 1.6 beta, and it's awesome (1.5ghz ondemand)
Some things that helped me a bit was:
-Calibrate battery
-Undervoltage (download system tuner and hit 6 times on the -12.5v button)
-Juice Defender ultimate (It works really good for me)
Hope it helps

Battery issues

I'm getting pretty horrid battery life. I'm not sure what to do to help improve? This is with brightness as low as possible. Screen time is 2.5 hours. Battery saving is on for everything beside regulating cpu speed. Rooted but with stock Rom.

There have been a few people who complained about this. It seems to be a problem with some of the phones. If this has been happening since you got it out shortly after, then it's probably the phone or battery. You might need to unroot and exchange it. Using battery tips or programs will only gain you about 10%.
If you're rooted try CPU Sleeper: https://play.google.com/store/apps/...wsMSwxLDMsImNvbS5ldWdlbmUzNzMuY3B1LnNsZWVwIl0.
It turns off one of the cores while your screen is off, which should help standby time.
Using a non-stock rom and kernel can also greatly help your battery, but it seems as though you want to stay stock.
Lastly, how's your signal? That's all I can really think of that would cause the S3 to have bad battery life. The S3 usually lasts a pretty long time.
Try GSAM battery monitor or Better Battery stats to find which app or service is drawing your battery. I've seen in other threads where giff_daemon and media server is causing lots of wakelocks and draining people's batteries.
Turn off sync, mobile data unless your actively using it, flash some other ROM and run Imos .07 kernel(aosp) or Kt747. Check what services are running. Freeze or disable ones you don't need.
Want mine to look like this unless I'm running an app.

Manually sync check everything.

Let not recommend custom rom/kernel etc.. Stock S3 should be very good on battery. You should find out exactly what drains your batter by using battery stats. Also enable battery saver mode and auto brightness. Turn off data sync, 4G, wifi, blue tooth and GPS (only turn them only when you needed) and see if it improved. Between using battery stats and turning off all the high drain options, we should able to pin point exactly what the draining source. A normal usage with stock rom, you should able to get around 4-5 hrs of screen on for normal usage.

Try setting up juicedefender, if you don't use your phone that often and battery still drains it will help. I use it at work since I don't use my phone, I have the ultimate version.

Battery difference with "scanning always available WiFi" on/off? Anyone test it?

Battery difference with "scanning always available WiFi" on/off? Anyone test it?
So currently have it on. Its suppose to use very little battery, but my WiFi keeps showing up on my battery useage with it normally at the 2nd/3rd highest battery drain. Has anyone done any testing with it on and off yet? I'm curious if they actually see a noticeable difference between the two.

Leaving WiFi on will always have a detrimental effect on battery use. More so if it's constantly scanning and not connected to anything.

You know I'm not talking about having the actual WiFi on itself right? I'm talking about in the advanced settings where it will use it to determine location when needed. Google added this feature saying it will improve accuracy and have very little effect on battery at all.

Yeah I noticed this. My 2nd day using the phone, I left WiFi on while not connected to any network, the battery lasted 5 hours, with like 1 hour screen on time.
Yesterday it lasted me 13 hours with WiFi off, and about 4 hours screen-on time. I was streaming the Laker game for like 2 hours via SlingPlayer too.
