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

Battery Life?

Is anyone noticing ridiculously bad battery life? About a week ago it started along with what i noticed to be Verizon throttling data. Could the throttled data be the cause? I'm talking 1030a, 89% battery. Then at 430p 13% battery with the screen off and no use. I mean not even pressed the unlock button once. The background info has been the same and rooted with apps removed since day i got it.
What are you guys experiencing?
Little Buddy Sr.

yeah my battery life sucks too. even with juice defender set on aggressive, it still sucks. it's better, but not much better. unplugged today at 10am and now at 56% at 730pm. that's with minimal texting and calling use and absolutely no browsing the web (not even fb app).

Still though that's 3.5 hours longer and used half the battery. And i didnt do anything for those six hours. Like basically that's a stand by time for six hours. That's a new level for bad haha
Little Buddy Sr.

7:30am - 100%
3:00am - 15% very lite usage. 1 call, some text msg, couple of responds to words with friends, lite email.
I'm rooted, running the decrapifed 1.0, adw ex launcher.

I believe you can switch your network to CDMA for 3g which helps with battery life..also dont leave wifi turned on OR bluetooth if you dont use it..task killer works damn well..makes my browser a bit quicker as well

Speaking of battery life....everytime I hit task killer it's always killing 17-20 apps... even when I'm not really doing anything what is the deal with that? How do I get this thing to stop running so much **** I don't even need...

I have also not been too thrilled with the battery life on the Revolution. It probably doesn't help that in my house the 4G is borderline and drops in and out constantly. I found a $30 extended battery on Amazon, so I'll give that a shot.
But the real reason that I'm posting is because I've been trying to "thank" thecubed ever since I got the phone. I haven't been able to figure out how and I finally found a post that said that you have to not only register, but also post something yourself before the thank button will show up.

Get an extended battery
there are extended batteries out there that are rated at 3000mah....this would give you a lot more talk time and standby time. Try one Good luck!

Are you rooted? If so, you can use Titanium Backup to freeze apps. Also, within Android, there are tons of triggers and events. For instance, when you start your phone, these apps open, when you connect to wifi, these apps open. Within TB, you can freeze a lot of the crap. Also, there is a program called Autostarts I really like a lot. Not well known, but great none the less. It will show you all the triggers and events. You can disable them there too. Do some reading and know what your are disabling, but why would you want Slacker to load every time connection status changes, right? Good luck, and if you need more help our want a detailed walkthrough, I can help you out with that.

Do a Google search for "Android Task Killers" and you'll find all kinds of articles explaining how these apps actually make the Android OS use more battery. There is a good one from LifeHacker that explains it in depth.
So if you're running a task killer, stop... The constant killing and restarting of apps will use more cpu cycles and drain your battery more. Android doesn't use any battery to hold an app in memory. They will launch faster, and use less CPU (which is what drains battery) if they are already in memory than if they are not. You're better off to have your memory full. I killed ATK a couple months ago after reading several posts by Cyanogen, and I not only got better battery life but also increased stability.
Second thing is try Juice Defender. I installed the Ultimate version of it and spent about an hour getting it all configured and my battery went from 100% at 8:00am and 20% at 6pm to 100% at 8:00am and 70% at 6pm with regular email checking a little web surfing, and a couple of short phone calls. I was pleasantly surprised with how well JD works.
De-crapified rom helps too. Thanks TheCubed!

Battery drained in 5hrs.???

Hey guys Thanks for stopping by, I've seen many posts like this which I really didn't want to post but I ran out of options... Im. Currently running on gingervolt 1.3/ blitzkrieg+ 2.6.35.7, I hope you guys have all the info you need. I leave it running over night and when I leave for work in the morning at noon its already powered off because no more battery... Please let me know if there's something I can do to make it last longer... I'm not the type of person that uses the phone all day.. Thank you

Should be in General not Development, And why don't you just shut the phone off until you go to work?

You can try: Setting the CPU lower with an apk like CPU master, CPU set, ROM toolbox, ect.... Turn down the brightness of your screen. .. Uninstall some of the apk that are always running in the background... Turn off LED message alert. Stop using apks like advanced task killer (unless you custom set it up to not kill system vital apk.) Turn off 4g unless in an area that has strong 4g sig. Recalibrate your battery after a full charge. Install GingerVolt 2.0. Buy extended battery (still $25 @ vzw website)
There are many different things you can do to get more battery life out of your phone... Look in the GingerVolt forum and check out where others have done. But get a custom to bringing your charger everywhere you go.

Not just turn off 4G but turn off data and wifi. These 2 radios are constantly working. The more time with them off the longer the battery will last.

My own experience and take is that daily battery life depends on good cell signal. I live at the fringe between three cell sites. My signal is typically two bars or less. At work I have a similar situation, but shielded by building opposite the cell side.
I always stay plugged in because my battery is always being used otherwise. My guess is that people who report much greater battery life are lucky enough to be in areas with good signal strength.
As an example, this morning I got up 1.5 hours ago, took the phone off the wall charger, rebooted it and used it a bit during my morning prep. I left home an hour ago with the phone plugged in to the car charger for 20 minutes (which charges at the lower USB rate). I have been at work for 40 minutes off charger since and now have 90% left on my EXTENDED battery.
At home reception is 3G most of the time. Work 4G.

yeah I agree, turning off 4G is not an acceptable solution....
GV2.0 unmodified with a cpu tool worked fine for me but I have gotten accustomed to having chargers with me wherever I go (home, office, car)
We are hearing battery life is much improved on ZV8, so maybe that will help too with the next GV release....

V8 battery life for me is now crap. I have gone from about 3% per hour usage to 7 to 10% usage and that is with almost no usage of the phone. This is sucking. I am about to roll back to v7 if this does not improve.

Not sure how your phone is different. Maybe you need a new battery or possibly a new phone. Forgot my phone at home during work today. I'm at 86% after 9.5 hours.

I've got the same problem he has except it got worse after I went to Gingervolt 2.0. From what I've read on here it seems that not wiping date may have something to do with that so once he gets the new update incorporated into Gingervolt I'll be doing a complete wipe and trying from there.

Killing a battery by keeping it topped off or cycling it. Which is the greater evil? This type of battery has a number of discharge life cycles. So, stressing by keeping the voltage at max or consume those life cycles? I don't know, but I certainly want to have it most available, and keeping it charged works for me. Some people don't let their fuel tanks go less than 1/2.
In the end, I have way more battery, extended and spares, to care if keeping it charged up is hurting the battery because I only have it until the next upgrade in a year.
Ideally, I would prefer to change the charge scheme so it wouldn't run the charge voltage so high maybe to 95%, to protect the battery further. But, in my time frame, doesn't matter.

I run JuiceDefender Ultimate and it helps quite a bit. I'm using it in aggressive mode on Gingervolt 1.3 ROM, and ran it with stock before that.

I personally don't think hes killed the battery.
I have two because they gave me a special on docking station that came with an extra battery when I bought the phone. Anyway I sleep during the day because I work night shift. If my battery is almost dead I pop a new one in before bed otherwise its at about 97 percent after I got home from work. When I wake up 5-8 hours later I've lost almost 50 percent. Sometimes more from either battery.
I check the batter usage stats and Android System is up at about %97 percent...
I have all notifications turned off except Gmail and theres no WiFi or anything.

Data drains battery, simple as that. I only turn on data for certain apps and a minute every half-hour. Does wonders for my battery.

You can charge up your phone in 1/2 an hour, why cripple your phone to gain at best 1 hour extra?

Well, I see it as me taking control over what my phone is doing... Everything still functions like it should, but only when I want it to.
And to be honest I haven't tried it on my N6 yet (as it hasn't arrived), but on my old phone it means the difference between my phone lasting all day or only until lunch.

None of that is really needed. Data doesn't drain your battery unless you're your cellular signal is horrible. I leave my phone with lte on and it doesn't drain.
Look into using a custom kernel such as Franco which can give you additional battery life. It's much more significant doing that than to use a app to control your phone.
No point in crippling your phone. It's a phone, use it as a phone.

I think the word drain is used far too often. Battery drain is not synonymous with battery use.

Yeah screen on time with auto screen brightness. Pretty much on LTE all day. Only disabled bloat apps.

Full day with it, unplugged at 3am and at 8:38pm cst, I am still at 48%. Now I don't use facebook or Tweeter so that helps my battery life. Wifi at work weak and slow so I am on LTE most of the time.

Same here. Only around 4 hrs with regular use. This device needs root.

Easily getting through a day with the phone. Most of the bloat disabled, moderate usage, Bluetooth/NFC/Wi-Fi always on, though mostly on LTE. I certainly don't expect this thing to last like my Note 4, but I'm pleased with the battery life. I get home with time to spare, and plug it in every night like any other phone, so its all good.

Root doesn't mean better battery life. My nexus 5 had about the same battery and got about the same battery life as my s6. And that's rooted, stock, slimrom, and cataclysm. My G3 has about 500 more mAh than the s6 and I get about 5 hours of screen time. Stock battery was better than cyanogen battery.
It's not 2012 anymore. Root is almost obsolete. It's good for app removal, rooted app functionality, and customization. Even if underclocked and undervolted it doesn't change dramatically. If u want a better battery, buy a phone with a bigger battery. MOST people don't look at their phone for 25% of their awake hours (if avg sleep is 8 hrs.) The s6 will give u 3.5-4hrs of screen time on 14-15 hours of use. That is plenty for MOST users

We badly need root. Rooting my phone has always improved the battery life and performance of your phone.

Battery life today was better I think. Screen-on time didn't even show up in the battery usage list, so i'm not sure how much it used. 20.5hrs since unplugging with 14% left.
This will definitely be a phone I'll have to get rid of after a year. With constant charging and a sealed battery, this device really doesn't have a long life. That's my main concern.

Someone in another thread turned off Enhanced LTE (Voice over LTE) under network settings and saw a much better battery life (or lack of drain).

I am experiencing insane WiFi battery drain. I am foregoing the use of WiFi in the mean time. Seems to help.
