Informal battery test

There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

My phone does great in standby as well, but seems to die quick when I'm actually using it. I've never had an issue with the phone dying on me though as I recharge every night. I think i had a little better battery life on miui than I'm getting now.
I know there are many many factors that go into battery performance, I'm just curious what other people actually get when using their phones.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...

10 minutes of on-line gaming (storm8 games) = 10% drain
WiFi off, gps off, mobile data on, screen brightness on auto, stock rom

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

My battery will drain about 5% if I even just leave it sitting for ten minutes... I JUST rooted my Inspire and flashed the RCMix3D ROM, and it almost seems worse. Have background data, auto sync, wifi, gps, bluetooth, all that stuff shut off, too. I love this rom, but really want to find one that improves battery life!

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.

Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks

From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.

[Q] Best ROM for battery life?

I get horrible battery life with nearly every ROM Ive used on my Sensation, sometimes drains 10 percent an hour with the screen OFF. I have all data off, no wifi on, no apps running, juicedefender ultimate, and underclock when screen is off, and I read about people who can get a full day while using the total potential of the device. I had the same problem on my old device, so I returned it to T-Mobile and still have problems on the device I got in return. I dont expect to get two days on battery, I just find it crazy that I can barely use my device without the battery draining rapidly. I've considered undervolting but every rom ive downloaded didnt support it, so I was curious if you guys know of any efficient ROMs that save a ton of power and can be undervolted. I'm not very experienced with this kind of stuff and every ROM ive used has been poor on battery life, so help would be appreciated.

I am using InsertCoin ROM and it is running fine.

I used to have a 3% battery drop per every hour the phone was sleeping on stock rom and ARHD ics. Then I tried Virtuous Inquisition and it fixed the issue. Be sure to install the rom with its appropriate radio.

ICS isn't fully stable yet, but seriously.. give that a try. My battery has doubled its lifespan. I have NO idea what htc/google did, but I get about 12 hours moderate usage and still around 50%. Getting 12 hours back then was what I was hoping I could hit! Now it lasts beyond my expectations
I've also read that you tried undervolting and everything. I just stayed stock and it's great, no effort! no custom kernel, OC/UC , it's amazing. If you read through the threads, I'm not the only one experiencing awesome battery
If you must know, I'm using InsertCoin but I think ARHD and all the other ICS roms will pretty much solve your problem

Hello, XDA-Community.
I bought my HTC Sensation XE 3 month ago.
First i must say, the Beats-headset has a very good sound, but it's bad quality.
2 weeks ago, the right headphone stopped working. I gave it back to Media Markt and they sent it back to HTC, i must wait for it-.-
but now the real problem:
i always have got a bad battery life! (lock at the attetchments)
i tried nearly all roms(really a lot), all kernels, i tried to underclock or undervolt an different govenors. i even bought an anker extended battery but it all didnt't changed anything.
after that, i tried to downgrade form fw 3.33 to 3.32 and to downgrade the hboot, but nothing.
does anyone of you have this problem too or can anybody help me?!
its so bad, i even cant get 10 hours with it..
2h and 33 min screen on time an still 9 percent of battery.

Based on your screen on time, that battery life isn't insanely bad. It's not good, but it's not utterly terrible.
Have you tried the simple stuff like lower brightness? Turning BT and GPS off when not in use? Keeping Mobile data turned off? Lower the screen time out to 15 or 30 seconds?
Those things will do wonders for battery life.
Also make sure you're not overclocking with a performance governor on your kernel. That'll burn battery like crazy. Use a more battery friendly governor with your kernels like Badass or even Conservative. And don't clock it up to 1.7 or anything nutty.

i never use bt or gps. only thing is mobile data.
screen is nearly always on lowest and if not, its auto.
time out is at 45 sec.
if i use bricked kernel, my battery life is better, but every hour my phone reboots less one time.
now i am on faux kernel, underclocked to 1.1 ghz and undervolted to -75. the govenor is intellidemand.

You could try to use a non-sense-based rom like cyanogenmod, for me there was a huge improvement.
Regarding your Problems with random reboots on bricked kernel, just set the minfreq to 384Mhz and it should be alright

both problems(battery and reboot) are still there after trying this...

How much gaming are you doing? Regardless of how much screen on time you have, games can drain the battery like crazy. What's your usage pattern like? Lots of web surfing over mobile internet? Watch a lot of movies? Games? 2.5 hours of screen on time isn't too bad, but it's not great either.
If all else fails, wipe all except SD card, install ROM, restore apps without data unless that data is extremely important to you. Also make sure your radio and RIL match with something like GetRIL. Match your firmware to your ROM base too (ie. 3.33 firmware for 3.33.xxx.xxx ROM).

Have you tried to put the phone in airplane mode during the night time. Or reset your battery stats?

2.5 hrs of screen on time isn't bad when you also had an additional 6.5 hrs of standby. But the biggest thing you can change to save battery is background data and auto sync. Turn those off and expect big difference. Also don't use auto brightness unless you have to. If your inside then turn it all the way down .

REMEMBER TO HIT THANKS IF I HELPED YOU IN ANY WAY, IT'S POLITE AND APPRECIATED.

Hi there, I had absolutely awful battery life on my stock battery! I understand completely what your going through. I did however find a solution . First let me say I've tried just about everything, turning down brightness , turning off sync, switching kernels, turning off gmail, yet still the battery life was awful! So finally I purchased a extended life battery, I choose Anker because the price was low. It did help but I still was not where I wanted to be. Then I decided to purchase a mugen 3500mah battery. It's expensive but worth every penny! Now with heavy use I'm on 100% for two hours. I can use my device heavily for 19, hours and still have 42% battery left ! It's amazing! I wish I got it sooner! It does come with a replacement back cover to fit the battery but my 4g signal is still strong, WiFi works perfectly , navigation works perfectly so no worries about the case interfering with signals. It does make the phone thicker but it still fits in pocket, and feels good in your hand . It does look thicker but who cares with this kind of battery life! Finally I don't have to worry about my battery! If your tired of worrying about battery life then get the mugen 3500mah battery. Buy it directly from mugen because there are too many counterfeit batteries going around on other sites. The downside is it costs 100 dollars but honestly its worth every penny. If your serious about getting a great battery then this is the one. I don't regret getting mine for a second! It makes all the difference in the world! I had to save up to get it but it was worth it. This battery will solve your issues! It solved mine ! Best wishes and hope this helps you.

I'd recommend that you don't delete the battery stats. The phone should learn over time and every time you delete them it has to start from scratch again.

but how to calibrate the new battery?
still having so bad battery life, after disabling auto-sync.

You calibrate battery by draining almost down to about 10% then recharge to 100% repeat this process about 4 times and battery will be calibrated. I read your not supposed to drain to zero although some people do during calibration. That's up to you. I read draining to zero can sometimes put the battery into a deep sleep and its very difficult when that happens to get it awake again. So I only go down to 10%. Hope this helps and answers your question.

As I understand it the phone/ROM won't allow the battery to be discharged fully to the state that it'd cause a total battery failure. Get CurrentWidget from the Play Store.
I can't remember the Full/Discharge voltages (~4.2V to ~3.5V) but not certain.
Just let the phone charge fully and discharge normally (let it get to a total turn off) a few times and you'll be fine. Please stop wiping the battery stats it just confuses things.

[Analysis] ROM-Battery results?

Hi,
Since all development thread are full of question related to battery. Can we try this?
1. Keep your screen on for 1 hr (or more?)
2. Keep wifi on
3. Keep radio/data on
4. Keep GPS off (or on?)
Report battery remaining, your ROM and version. Your battery stock/anker/other.
Then we average it out and see how it compares .
I know there is a thread already for posting battery results but it will be easier if everyone submit comparable battery results.
And me (or someone) analyze that to get some useful data.
Let me know what you guys think.

Screen on with Wi-Fi on, radio data on, gps. On. One hour with fully charged battery and I'm at 100% reading still. My rom is paranoid Android by Dragun Korr. My battery is a 3800mah, by Mugen. I have found having the big battery to really make a difference for Me. Hope this is helpful. Best wishes

Then maybe we need data for longer duration .

Hey, this is a great thing to want to try. A lot of variables come into play though such as apps installed. Consider: GPS on and not in use does not affect battery life. If an app is constantly polling for your location in the background then suddenly that's not the case anymore. This might be bets done from a fresh install perhaps with no GAPPS where applicable.

i don't know why but aosp-based (non-sense) roms always eat my battery faster than sense-based roms, even sense 4 roms work better.

Battery life bad even on Anker 1900!!! Help!!

Hi all,
I brought my HTC Sensation z710e about 14 months ago, and I'm a pretty heavy user, so battery life took a hit.
After about 8-9 months i got 4-5 hours screen on time on the stock battery. About 7 hrs heavy usage. I tried formatting the phone, and kept an eye on battery abusive wake locks, but to no avail.
To rectify that I've tried various roms (Elegencia 4, VipersS 1.6, Albinomans CM 10.1) among a few and also tried undervolting the phone. Nothing.
Then about a month ago, I brought a 1900mAh Anker battery which according to a lot of XDA threads is the problem solver for all battery issues.
I've been using that battery with Albinomans rom, and I have tried wiping battery stats to ensure the battery starts from a clean slate, but still I get barely 7 hrs, far from the promised 2days.
That leads me to conclude that something is wrong with my setup. And having tried many roms and kernels, formatting my phone and doing most other stuff suggested on the XDA threads, I cant work out whats wrong.
If it is a hardware issue, is there any way of finding out what it is, and what would be the way to rectify.
Any help would be higly appreciated
(although I've been and rooting and playing around with my phone for abt 3months now, this is my first thread on XDA. It may be a little unorganised in the way its written. If i've left any info out plz let me know. Thanx)

hello, if you use many applications that constantly require the 3G part of your mobile , it is quite normal ...
With my stock battery, i'm about 20hours and more but if i play games for a long time it's normal that battery drops.
I even think that you can be happy that your battery takes 7 hours using it a lot.
Try these CPU settings :
Governor Lazy or Badass
Min : 384Mhz or 432Mhz
Max : uses frequencies between 932 to 1188Mh
When u change ROM try to wipe battery stats before first start
Before u change the Kernel, make a Full Kernel Reset. Flash new Kernel

This part all rings true. You cannot measure the battery life by how long you go between charges. That's almost irrelevant information because if ti's set up properly the phone will use very minimal battery when the screen is off.
The proper way to measure the battery life is by how much screen on time you get plus phone talk time between charges. With an Anker on Albino's CM10.1 ROM that should be 3 to 5 hours depending on a few other things. If that 3 to 5 hours happens all at once, then you'll need to recharge in 3 to 5 hours. If you use it sparingly over 2, 3, or ever 4 days before you've use it for a total of 3 to 5 hours, then it'll last that long between charges.
The 2 things that use the battery are the screen's backlight and the cell radio. Those two things are the battery users. Bluetooth and Wifi are too. But theoretically you're not using bluetooth or wifi unless you are talking on a call or having the screen on. So you can still measure by the scren on plus talk time. And if you use bluetooth and wifi a lot your total use will be closer to 3 hours than 5 hours.

This part is not true. It has no effect on anything. And when you install any ROM the battery stats are going to get wiped anyway because you are replacing the entire contents of the system directory.
No amount of wiping battery stats, calibrating batteries, or any of that mumbo jumbo is going to help. It's all snake oil.
Also keep in mind that you do need to give a new ROM 3 to 5 full charge and discharge cycles before you really see what the battery life is like. If you're jumping from ROM to ROM every day to test battery life you'll never get an honest look at what batter life is like on any of them.

On albino's ROM? You only have 2 options. The one that comes with it, which is perfectly fine. Or SultanKernel, which isn't terribly different. But the install process of sultan gives you more configuration options.
