I want to post my experience of MAXX battery life here. I am using International RazrMAXX (GSM only) bought almost 5 months back from eBay. Still I want to post it here and don't want to open a new thread in GSM-Phones discussion, because 1) Very few GSM only MAXX users here 2) Droid_RazrMAXX is almost RazrMAXX wrt GSM capability + Battery.
I want to share my battery life experience for many times earlier, but my wife used to charge it on the second day itself when the battery level was around 50-60%. This time I have managed to use the phone for three days and taken screenshots and hence sharing here.
Let me first describe my usage pattern. I make lots of phone calls (on UnLimited 1299 plan), play games/videos 20-30 mins a day, browse using WiFi mostly, Sync ON and DATA mostly OFF (I use BSNL 3G on GNexus), Coverage of Docomo is bad and switches to Aircel in zero coverage areas -- So NOT steady and good network signal.. But in this example, I have less voice calls usage than earlier (so comparable to general users) as I am in wedding function for two days.
Result:-
3 Days - 0 Hours - 33 Mins - 3 secs on Battery and 16% battery life remaining (Please look at top for the battery Mod to accurate 16%) The slight bump in battery life is due to connecting to computer by USB cable for copying the screenshot after 2 days usage. Thats just 4-5% increase from 32% to 37%
Screen Time:-
Screen used 43% of battery life and Screen ON Time is 4 Hours - 12 Mins - 38 Secs
Voice Calls:-
Upto 28% of battery eaten by voice calls and Total duration is 4 Hours - 0 Mins - 5 Secs.
Please note that even in same length of calls, calls duration in GSM will be less than CDMA as in CDMA call duration starts almost immediately after pressing Green key, whereas in GSM the duration counter starts only when the receiver attends the call. But GSM mode uses less battery for voice calls comparing CDMA mode.
Games:-
Playing GrannySmith for just 37 Mins - 1 Sec eats 3% of RazrMAXX battery life (May be 5-6% for other phones).
----------------------------------------------------------------------
I will try to post my next usage with 2G data always ON, but in general its NOT affecting a lot imho and I earlier got FULL 2 days usage with still 25% battery life as spare.
For me battery life is the most important feature in any phone and won't waste it unnecessarily. I have already rooted MAXX (in ICS) and removed bloatware to keep it in shape.
I am sure RazrMAXX_HD will be having better results and I am too eager to buy it. But its Locked Encrypted Bootloader is stopping me from getting one. OMG GNexus comes with sh!tty battery life (needs to charge it twice a day) and the phones with Jumbo battery is coming with Jail attached.
Now I am seriously considering GNote2, esp GNote2_N7102 Duos (launching tomorrow on PRC), which is best of both worlds (and size smaller than GNexus+MAXX combined in my shirt pocket)
