I've been trying very hard to track my batter life over the last two weeks, since it "appears" that my btty is crap. Love the phone, very much dislike the btty. I'm coming off of a BB Storm, and my usage pattern is the same as it was with that device. On my Storm, I could go two days with my usage pattern, and as long as I charged it on day 2, I was usually GTG. Not so much with my DINC. I'm fortunate to get 10 hrs of up time on a single charge!
So lately have been trackinng some usage stats. Things like: home at 6:30, loss of 20% btty power in 5 hrs (phone asleep, no WiFi, no calls, no text etc). Went to bed btty at 37%. Woke up and btty is below 9%. Went to work at 6 AM, by 1, phone showed 7 hrs of up time, 1.75 hrs of awake time and btty was down to 52% (only one very short phone call, a few texts, no internet etc etc etc).
Walked in to VZW store, first question that was asked is "Are you using ATK?" I patiently explained that while I did have a TK loaded (ES Task Manager) I don't use to to Task Kill because with Android its not needed. I was asked 3 times by 2 employees if I had ATK and used it. I showed them Settings --> About --> Battery and it was a revelation to the low level sales guy I first spoke to and the store manager. Neither of them had a clue about seeing what the battery was doing, up time, awake time etc (Thanks Android Forum for teaching me this cool stuff!!). In any case, I was able to show them that there were no random apps sucking btty pwr or CPU clock cycles and they conceded I "might" have a btty problem. They had no batteries in stock and offered to order me a new one.
I am almost at my 30 day window and asked them if I could take the btty out of the DINC demo that they had. Apparently, they didn't think of making that swap! So they agreed and I made it plain that I would monitor my usage for a week and if it still sucked, I would expect them to order me a new battery.
I love the phone, but the btty stats I've been getting are awful. I'm sure "part" of the problem is my work area is bad for reception (ie searching for signal and TOS is high) but I've done all the tips n tricks for app monitoring. I bought a SmartPhone to be..well...smart, not to have to turn everything off in order to be able to have enough juice to make a call or send a text. I am hoping that perhaps my OEM battery was just...bad...and perhaps this replacement might improve my stats. All I am asking for is a full 14 hr day of use; I can handle daily recharging.
