Battery Life- An experiment

Anderson Did an experiment to see how far the battery life can last on normal usage.The battery power was monitored using the app "Battery Monitory Widget"
And he came to the conclusion that The battery life could well last more than 2 days if you use just the communication tools (whatsapp, Facebook, sms) on a 2G network. With heavy data usage, the battery power got zapped out rather quickly.
You can have a look at the full experiment

I'm kind of experimenting in this too..
Today i unplugged my phone this morning (6am) and its dropped to 97% now @ (3pm).
So thats only 3% in 9 hours..
I use Facebook widget which updates + Twitter widget same setting (both auto update every hour)
I sent about 10 text messages (also received about that amount) and made 1 phone call (about 3 minutes)
All this on 3G network, i dont save on 2G/3G setting

2G coverage is very suboptimal in Switzerland, especially if you are using a Sunrise.ch contract. Their 2G performance with Edge is about 100kbit/s for download. This is a joke. I am not able to use a phone with 2G and enjoy it. Therefore whenever possible I have to switch on 3G (which is of course also not great, but at least it is much faster).
Therefore, 2G is not an option at all for me.

I am running stock on mine and I seem to at least have found some form of "battery" drain. Trying to reproduce the usage.
But I charged my phone fully, and then restarted it and "at the moment" it is holding its power sorta alright. But when I use it normally it lasts like 7-8 hours before needing a recharge, even if its just laying on my desk and not being touched.
Ok testings done. These figures are after a reboot and where I have more or less left the phone laying on my table only having a short call, and otherwise reading a few emails and responding to a few texts. The entire time autosync was on, as well as 3G Data.
1H30M -08%
5H30M -30%
8H20M -50%
11H00M -68%
12H15M -74%
13H08M -79%
14H15M -85%
15H20M -93%
At which point I stopped the test and then put my phone in the charger. Tomorrow once it is done charging I will start up all the stuff I normally run on it, charge it to full and see how well it does there when I am not using the phone at all. Quite frankly I expect a large difference simply because that is what I have seen, but starting program and then exiting said programs and leaving the phone on standby "should" not impact consumption in my view at least.

I think there is something bad with my battery, because Battery Monitor Widget says that my battery is a 1200 not 1500, without doing nothing at all it lose 1% per hour and suddenly in 10mins drops like 6%, so in 8hs aprox from 86% goes to 68% (the phone doing nothing)
I have 3G always active, whatsapp and gmail, just that. Will try to do the test again with 2G, but what I don´t understand is why it says 1200 instead 1500.
Should I get a new battery? could be deffective this one?

CM7 is the best for me

CM7 seems to be really good for me, i used 28% of it with medium-heavy use (no games, but wifi always on and a lot of playing about with) in 5 hours and at night i lost 3% in 7 hours sleep with 3G on. Not fully stable but seems better than sacrificing the smartness of my smartphone.

Lost 0% 2 days ago when sleeping for 9-10 hours i think
Today i lost 1% when sleeping for 9-10 hours
I am using 2g since i don't have 3g connection in my house.
It's a bit unstable but battery improvement is more important for me then some little bugs

No problem .
The O2X does not have good battery management, so it will drain.. getting usable results with mcr r15

I have found it depends on the signal strength. At home and work I consistantly get 4 bars and 3G signal all the time and I can go 2 days on a single charge.
When we went on vacation recently, I was only getting 2 bars but a 3G signal and a single charge didn't even last me 10 hours.

"hows the battery on this phone?" Well - it's black!
It's a very strange question...
"hows the battery on this phone?" compared to what?
To a neuclear power plant it's rubbish. Compared to my wife's Desire it's fantastic.
It all depends on several parmameters and setting. Opdate stuff all the time like mail, Facebook, Twitter, takes a lot of power. Screen brightnes also.
My battery last about 3 days.
But still a very strang question...

It's OK. Comparing to Desire, it's better. And it depends on the strengh of signal.

its much better than the desire in battery but not better in Signals...

[Q] Battery drainage

this battery drainage seems to be a big problem with HTC one, is it really as bad as people/users are saying?
if the drain is that bad on the standby should i withhold getting HTC one? im out of the house for more than 14 hrs per day and a juiced up phone is what i need!
GS4 or ONE?
please advise

Actually the battery isn't a problem at all with the One! It is way above average for todays smartphones (not counting in the Note II)
You will generally get 6h of screen time with "xda-user" (most likely higher usage then the average consumer) which is amazing.
I leave the house at 7am and come home at around 10pm, that is 15 hours and the One has been holding up great!
I can't see the GS4 being any better. AMOLED + bigger screen = more power consumption (you need higher brightness etc.).. and in my eyes the One is the better phone over all too... so my advice is to get a One and you will be really really happy!
You may still want to invest 40$ in a portable external battery so you can charge your phone on the go .. just in case

Wait for GS4 Exynos OCTA performance tests to decide.
Maybe the OCTA will be more power-friendly.
Nevertheless, AMOLED 5'' screen of the GS4 seems to be better than the HTC One's . Even the brightness is not an issue anymore cause the new AMOLED is seen better on sunlight than the SLCD3! It suprised me cause the S3 was bad on sunlight. Source: http://www.gsmarena.com/samsung_galaxy_s4_vs_htc_one-review-913p3.php

Thank you, but was the incremental loss of battery while it's on standby?? I even gsmarena says that the standby time is pretty horrible..

Just looked at my phone after leaving it on overnight for 8hrs to see a 4% drain, now I'm no expert but that seems pretty darn good to me.

Screenshot for the battery drain please?
Thnx given

I still have my 2011 HTC Phone here with 1500mAh battery and I get like 0 to 1% battery drain overnight.
Although I know someone there who get results like this with HTC One so the device is not an issue. Just trying to say that SmokyM79 might have wakelock issues there.

Didn't manually turn any data off the one has sleep mode which turns off data after long periods of inactivity, I have that checked, as for wakelock I'm comfortable with 4%.

The One gets better battery life than the GS4. Rogue apps holding wakelocks won't help either way.

On the related subject of monitoring battery consumption, I have used battery monitor widget since I owned my first Android phone , a Desire HD, however it doesn't measure current correctly on my One.
Does anyone have a recomendation for an app that currently supports the HTC One ?

[Q] Real life HTC One talk time, 5 hours?

My several day old HTC One is a fantastic phone (best I have owned yet), but I'm having to be very careful to keep the battery lasting an entire day.
In particular I am noticing that voice calls are the biggest drain on my battery.
2 hours and 20 minutes of talk time used 55% of my battery life yesterday.
I have read multiple sources with tests pegging the talk time at 14 hours+ (AnandTech, HTC official).
Is this typical or is there potentially a software or hardware issue?
I haven't done any serious tweaking to the software, and am running powersaver and have screen dimmed to 30%.
Thanks!

You have to see a lot of thing...
1) You had the full signal for all the calls?
2) Your phone was all time with the idle screen?
3) Did you have 3G or 4G on?

Details
I have three bars usually. I am always in 3G. As far as idle screen sometimes I am browsing while phone call is happening.
Does the strength of the signal effect talk time?

Strength of signal definitely affects the talk time. Also if you put the phone on 2g mode when you are not using data and just talking you will get a better battery life. Check for wakelocks as well. I also discovered when I was using htc sense launcher my app usage was about 89% but now I'm using smart launcher and my app usage is 70% and I'm getting better battery life. I've also disabled the maps coz it has a lot of wake locks.

Also, in my opinion, is the best phone I already had and I have been a iPhone fan for a longue time... With LTE one is very difficult to manage the battery for one day... If you can't charge during the day you are in trouble... Other complain I have is the high temperature on the back if i'm using for a longer time....

The tests for the timings are done with voice calls and no screen on. If your using the screen as well its double trouble

That's really low compared to yours. Also, using the speakers eat up a ton more battery, and if the screen is on as well, well that's another issue

I think I figured it out...
In case anyone else reads this thread, after some testing I think I found out what was causing the huge spike in voice app usage.
I now believe that playing music through the phones speakers counts toward the usage of the voice app.
When I use the speakers, huge battery drain. When I don't it's ok.
Hopefully case closed!

[Q] HTC one battery

Can anyone with an HTC one tell me about how the battery life is on yours and what helps make it go longer? Because I would call the battery on mine awful.

how does one describe awful? i think mine is good, my definition of good is about 20hours of usage and 4 hours screen on without any tweaking or power saver

My brightness is all the way down I'm on WiFi and I've been browsing the internet for 35 min and in 35 min the battery has gone down 20 percent.

you cannot judge the battery based on short bursts of usage, provide some information when you have used the device for a few days, otherwise you might get banned from this forum

60% left with 2 hours screen on is alright

I just switched from iPhone 4s and 2 hours on would have only drain my battery maybe half that at most

so by your comments, iPhone 4S would be at 50% after 2 hours and your HTC is at 60% after 2 hours?

No I'm saying my 4s would be at 80percent easily

Great battery life

I have no problems making it last all day (Unplug it when i wake up, and charge it when going to bed. Don't need much sleep, so on average thats an 18 hour day). Most of the times I have around 40% left.
Yesterday I was on a Skype call for 2 hours (voice only) and it used about 25-30%. After that still lots of messages via viber which meant waking the device often and quite a lot of screen on time. Also played a game (Mini Motor Racing) for about 10 minutes, was on facebook from time to time. All this mostly on WiFi. Actually used the "regular phone function" twice for about half an hour total.
When I got home I had ~25% left.
My phone is rooted and has a custom rom on it: ARHD 9.4 with ElementalX Kernel. (slightly overclocked, cant remember exactly, but I think I mostly went with the default/recommended settings on the kernel)
What really improved my battery life was to stop using Battery Monitor Widget Pro, even if I love graphs and stats etc.
Right now I'm using GSAM Battery Monitor to keep an eye on apps misbehaving.
The phone seems to do a good job handling screen brightness. Sometimes I turn it all the way up using power toggles.
What can really bring down battery life is turning on Best WiFi performance in the advanced WiFi settings menu. So you might want to check if that's turned off. My WiFi / data is set to be always on.
Hope my little tips/experiences help you a bit. This phone is truly the best one (in the smartphone department) I've ever had when it comes to battery life. It even has my girlfriend wanting one and she's had every iPhone. Of course I take great pleasure in letting her know how awesome this phone is.
