Four days’ charge on an Android

&gt; Cycled the battery. After running the battery calibration app, I let the battery drain all the way to 0% (phone shutdown) and then charge it back to 100%.<p>This is bad advice if you want your battery to last longer until you need to buy a new one.<p>Full discharge cycles might give you a slightly longer charge for the next cycle but they reduce the overall lifetime of the battery as much as 3-4 drain&#x2F;charge cycles between 20% and 80%. A battery that continually runs 0% to 100% drain&#x2F;charge cycles will only live 300-400 cycles, versus a 20% to 80% battery that may live 1200 cycles.<p>You might think the tradeoff in battery lifetime versus charge duration is worth it but as the battery loses lifetime, its maximum charge will be reduced so you&#x27;ll quickly have shorter charge durations.

They&#x27;re getting 4 days by basically not using the phone.

I got ~40 hours yesterday on my HTC one X by doing nothing special. My phone still had 6% left when I plugged in.<p>The 2 days prior to that have been busy days at work for me and I have used the phone for ~3 hours (1 hour phone calls, 2 hours browsing &#x2F; reading stuff).<p>I did not disable any radios. I was on lte the entire time, bluetooth was enabled, my email and twitter were syncing as well.<p>Perhaps Android 4.3 (and hence CM10.2) have improvements for battery life after all ?

“This includes turning off radios when there is no data activity and other services as needed. ”<p>Yeah, right… Forget about push notifications, push emails, IM, video&#x2F;VoIP calls, background updates.<p>Why not get a feature phone then? It lasts weeks between charges.

Am I reading the graphs correctly that it states that in 3 days OP only used Chrome and Gmail for roughly 9 minutes each? Yeah... don&#x27;t use your phone, and OH MY GOSH, the charge lasts forever!

If you don&#x27;t use much mobile data turn off 3G&#x2F;4G, letting 2G take care of voice and slow data.<p>This saves much power.

Not sure if this is the place for this but with my Galaxy Note 2, I generally get about a day and a half with moderate to heavy use, including not charging it overnight. I generally charge it overnight every other night and sometime plug it in for a few hours during the day.<p>I have not tweaked any of the settings and seldom use the battery saver option. I never use Bluetooth as I have no need for it. None of my apps are authorized for GPS except Google maps or FourSquare--I just have no need for most apps to know where I am. I do make sure to turn off wifi when I am outside of my home and using cellular data. If there is a weak cell signal and wifi available, I will turn it on. This isn&#x27;t scientific but I feel going in and out of wifi signals does drain the battery.

S2 is at least 2 years old. Whatever battery (1650 mAh) it came with is probably due to be replaced anyway.<p>Just get an extended battery such as Qcell [<a href="http://www.amazon.com/QCell-Samsung-SGH-i777-Extended-Compatible/dp/B006SK5GK0" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;QCell-Samsung-SGH-i777-Extended-Compat...</a>] (a whooping 3600 mAh!) and have same 4 days charge with all the updates&#x2F;gps&#x2F;bluetooth&#x2F;etc enabled, all the time.

I&#x27;m very satisfied with the battery life of my HTC One. I use it quite a bit during the day (a few sessions of Duolingo per day, HN frequently, the odd email&#x2F;chat, etc) and it&#x27;s still at 40-50% at night (I charge it anyway when I&#x27;m asleep, though).<p>It&#x27;s currently been on battery for 18 hours and it&#x27;s still at 23%, and this includes listening to audiobooks for an hour in the car, etc. It&#x27;s pretty great.

tl;dr if you hardly touch your phone, it lasts longer between charges.

What&#x27;s your screen on time? Most phones will get 4 days easily if you never use them...

If I would keep screen off, turn off any updates and receive no calls I&#x27;m pretty sure I will get a week with out any special roms or apps. But what&#x27;s the point to have a smartphone then?

I hate post like this, no one cares how long your phone last when you never use the thing. At least once a week theres a post like this over on &#x2F;r&#x2F;android &amp; &#x2F;r&#x2F;nexus4

Depends on how are you using your phone and what applications you are running. Try to use G-maps and facebook for a couple of hours and your battery will be empty.

I still have a G1 with an extended battery, and it gets charged once-twice a week. I use it fairly regularly, so it&#x27;s not jst standby.<p>Underclock, people, underclock :)

Don&#x27;t play Ingress.

What&#x27;s your screen-on time in minutes or hours?
