Rediculous Battery Life!!!

This thing is a beast. I have 30% battery left and I have been using it for 41 hours without charging it. And I use it pretty heavy on sundays and on 3g all day saturday. I think it's got the best battery life of any device i've ever used. How are other peoples battery life?

Can you post your battery usage please? Just interested what you've been using in those 41 hours. Seems incredible!

This is about the exact same results I get. I had about 30% left yesterday after two days and 4-5 hrs of usage.

I pushed about 36 hours before the device shut itself off. Medium to Heavy use (lots of browsing, some games, all around tinkering and playing in numerous apps), and a decent amount of that was standby.
Over-all, I'm very impressed with it and it has completely replaced my laptop (sold it before I got the Xoom, actually). I was actually having a hardtime leaving it off the charger because of how used to I am having to plug my devices in after a few hours of heavy use.

I did a real world test for my xoom this weekend. I used it as i "normally" would. when I wanted to do things, I just did - browse, played games, etc. I used it saturday night to show pictures of a new house to lots of people. Basically, how I would use it if I wasn't specifically testing battery life. Long story short, i went all weekend without charging. Charged fully at 4pm Friday. plugged in Sunday at 11pm with 20% or so still left.

with all due respect that's not accurate. A more accurate usage of batt life is 'display usage'
I get about 7 hours batt life. I was at least expecting 9 hours

9 is a little too much i'd say. It really depends on what app you use and how much power the cpu takes out of the battery. For example, simple web browsing and apps aint gonna run on 2 cores. Gaming on the other will though. And real life usage is really what matters.

I try to keep it off the charger as much as possible....i let it run down to about 30-25% give or take before I charge it. I want to keep this battery in as good a shape as I can.

My Xoom has awesome battery life... I am satisfied completely.

[Q] Absolute Best battery?

What rom (stock sense look) has the best battery overall. I rooted my moms evo to get her a great battery life but it still seems to be dying really quickly. I am using 4.3.1 kernel. She's only getting around 6-10 hours of battery before she has to charge it. I had the evo before and could get a full day and a half before charging it. I can't remember my setup since I switched to the evo shift. Any suggestions would be greatly appreciated, thanks.

im using the cm7 rc 2 whatever kernal is package there is PHENOMINAL im at 60% @ about 12hr..... Moderate use between wifi and 3g

That's the best you're gonna get with NORMAL usage and a REGULAR battery. All those users that say they get like a day or two are full of it. They get that long because their phones are sleeping most the time. I've used EVERY rom/kernel combo out there and the best I ever got was about 15 hours. I literally use my phone all day while at work from browsing, texting, calls, facebook ,twitter, and games. There should be a definition for moderate. I consider myself a heavy user; unplug at 7am and my phone last until about 6pm with about 20% left. Its not going get any better than that for a moderate to heavy user. From sense to aosp with the stock battery I just never achieved better results but I'm pretty happy since I get to work at 8am and get off at 5, buy 7pm its nearly dead and I just plug it up. You should invest in an extended battery imo.

I agree to a point. I mean, it all depends on usage. I can believe someone with light-moderate use can easily get a full day with the right setup. I do it now with CM/Savage, but I'm definitely not a heavy user.
I do see some people make wild claims of 2-4 days without a charge.. and I think it's possible IF you don't use your phone or you turn everything that makes it a smartphone off. Which is pointless IMO.
Nobody can really give you the perfect setup because every EVO seems to behave differently. We can only make suggestions. Make sure your mom s awareof all the things that can drain battery (push notification, updating widgets, weather updates etc etc). I would then research a good sense rom/kernel because CM7 is a definite WIP with different issues for different users, it may turn her off.
Maybe check out MikFroyo or Myns rom. I hear a lot about how good they are.

+1, its just crazy I see people throwing crazy hours out there lol. I think if your phone is sleeping 75% if the time then you shouldn't even talk about your results since that doesn't fit into the norm for usage. Most people check their phone like every 10 mins(don't quote me) I know I do lol. People throw around like 36 hours and even longer its insane to me.

Sent from my PC36100 using XDA Premium App

I don't know about not being able to get more than a day of battery life and use your phone. Using MIUI with a Savaged-Zen kernel I was able to go almost 2 days without even plugging it in once (I'm specifying this, because I've seen screenshots where people claim crazy battery life, but the graph clearly shows that the phone was plugged in and charging several times throughout that time period), and my display usage was still 44% of my battery. That was still minimal usage for me. I posted the screenshot in the MIUI thread if you care enough to check.
I do mostly agree, though. Most people posting outrageous battery life have display percentages around 5-10%, clearly never removing the phone from their pockets.
Anyway, as for the OP, the biggest missing variable is that we don't know at what percent your mom considers it necessary to charge her phone. If she plugs it in around 50% to be sure she can make it through the day, that means she could have gotten another 5-8 hours of battery life (assuming she's not draining it down to 0%). This fact could make the difference between bad battery life and a paranoid mother.

Try the ava froyo z3 I love it best rom I've used so far so guess I'm sticking with it o and get her juice defender with ultimate juice and lock it down so it kills anything she's not using

I agree with most of you people. Initially went to FreshEvo by Flipz when I rooted and battery life did not change much from when I was running stock. I have since switched to CM7 and battery life is significantly improved. Now getting 12 hours on a single charge with moderate use. I always turn 4G and wifi antenna off when not performing any data-intensive use. But I refuse to kill my 3G data connection when my phone is in my bag or desk while at work. Reality is that it IS a smart phone and killing the data to save battery life defeats the smart phone bit, no email no Facebook syncing no MMS etc. The only time I kill 3G is when I am in the mountains skiing.
My problem is that I work a 12 hour shift so 12 hours of bat life is not ideal. I have invested in an extra charger but would obviously be happy to not use this. I have heard lots of testimony that the savaged Zen kernals show some promise in improving bat life. When CM7 final drops I plan on flashing one of these kernals with the new ROM on wipe. I will stay away from the SBC version though for fear of improving battery charging but having my phone melt down or pop on the night stand next to me while I sleep... or worse in my pocket!
I will report back if I get any significant results.

im suffering a bad battery right now.
my phone will ran out of battery after like 6 hours' use. it's not as good as iphone 4, but not that bad. all the android handset dont perform good on it. but my battery went down to 85% from full charge after 8 hours sleep. any solution to this? another problem is that when i browse xda on my phone, only 12 % run out after 1 hour's use. but when i play the bakery story, the battery go down 1% every 2 minutes.
i just want to know this happened. maybe the game eat more power, but not that much i think.

In regards to browsing XDA for an hour vs playing the bakery story, it's likely because XDA is much less CPU intensive. When the CPU is being stressed, the battery gets eaten up pretty quickly.

Post your Battery life here

I don't see a thread like this for the T-mobile HD2 so I figured we can have our own.
It would be nice if you included the following with your posts:
screenshots including on screen time, information about your rom, kernel, etc. and estimated talk, text, browsing, and gaming time, and what brightness you had your screen on (auto, full, etc.). If you use something like SetCpu with profiles list your profiles and settings here too.

I get about a day on mine running Nexushd2-ics-cm9-hwa-v2.9a. I use setcpu to fine tune and use between 4 and 5ma on standby according to currentwidget. It is disappointing to see such a small battery in a power hungry phone. I do have the larger HTC battery but it makes the phone too big and bulky for me.

Thanks for the screenshots, how much battery life do you get by one recharge.???

Screenshots don't say much, I think, as the use of the phone is always different.
After charging I can game about 4-5 hours straight on full brightness for my battery to be empty.
With a lot of standby and only screen on to Whatsapp/Kik/Text and brightness on 'automatic', it can last for 1-2days.
Only listening music all day it can last about a day.
Standby only it can last almost a week.
ROM: Xylon 4.2.2
Battery Capacity: 1230mAh (stock battery)
Charging using an external charger because the USB port is broken.

[Q] Battery life.. (android system)

Hi all.
Just a quick question. My battery life is great but i feel like it could be much better. Here are my current stats as i write this.
With this its saying i will get under 4 hours screen on time, i wouldnt say i was a heavy user. I use my phone quite a bit but i wouldnt say it was alot.My biggest problem is with the android system anyone else have it as such a big drain? Somedays its sat up at 40%
Anyone know what i can do to rectify this? Im currently not rooted..
Thanks in advance
Liam

There are just two possibilities.
LG stock rom is so bloated that it sucks most of battery or GRAM feature is so good that screen time is not really problem anymore.

Forgot to mention, my screen time was 2hr 30 so probably looking at not even getting 4 hours screen on time.. Gonna have to guess that it's the stock rom sucking up loads of battery? Would that cause the android system percentage to be so high?

I'm having the same issue here.. Getting 4 hours screen ttime though...

I can easily reach 6 hours screen on time. And I'm a heavy user and by no means try to save battery. multiple social networks, emails syncing etc often streaming music and watch videos and brightness set to a constant 75%.

Strangely, for me, when I go over ~2h screen time the Android System drain is taken over by the Screen drain. This being said, I never got over 3h30m of screen time - this is with about 10h WiFi (including overnight => ~2% drain) and about 7h 3G. I have noticed plenty of crap among the kernel wakelocks, but I lack the knowledge to remove them in the source code and rebuild the kernel.
Also, BBS is among the apps that trigger a Qualcomm bug regarding sensor kernel wakelocks (sns_async_ev_wakelock), which, obviously, lead to more battery drain.
All of this is not really acceptable coming from a company like Qualcomm (the sensor bug, in particular, is present ever since the S3 QC version...).

I'll second that Greenify is pretty good at saving battery.
I too have had a screen on time of 6 hours 11 mins over a duration of being off charge for over 14 hours
I'm using StockMOD kernel but the ROM itself is stock as i can't seem to get StockMOD rom to boot.
Also if you Root try TricksterMOD and use multicore savings etc maybe get a bit more life from your battery
Hope battery life gets better for you as it is an awesome phone would be nice for you to enjoy it as much as the rest of us
