I got my battery Friday, so I've had it less than a week, but I'm loving it so far.
But the difference I'm seeing isn't due 100% to the battery. Based on what I've seen so far, the "bump charge" technique that's been described on the forums (and I describe below)
definitely seems to make a difference.
My experience with the new battery:
I charged it for 9 hours with the phone off before ever turning the phone on with this battery installed.
I had a hard time killing the battery on Saturday and Sunday before going to bed (and charging the battery again). And I didn't go to bed on Saturday night until about 3AM, to it had a really long day with pretty heavy usage.
I was absolutely loving life.
Sunday night I left the phone on overnight while charging (I use the phone's alarm clock). But when I got up I turned the phone off and plugged it back in while getting ready - probably for over half an hour.
Monday the performance was quite impressive. I don't have any specific numbers to share, but I went the entire workday and well into the evening without charging. I should mention that I actually bought a couple of extra charging cables from monoprice because, back when I was using my stock battery, I was plugging my phone in right after lunch everyday because it was nearly dead. For the record, I get really crappy reception at my desk. (It's almost as if sitting amongst hundreds of computers on the ground floor of a steel-frame building is bad for reception....)
Anyway, here's the critical part that challenges this battery's super-awesomness:
Monday night and Tuesday night (heading into Tuesday's & Wednesday's workdays) I charged the battery the way I had been charging my stock battery. That is charging it overnight with the phone on, then unplugging it in the morning and not plugging it back in until the battery got low - usually about 5-6 hours later. On Tuesday & Wednesday, this battery still outperformed the stock battery, but not by a lot. I probably bought me an extra 1-3 hours - which is about what you'd expect given percentage increase in the battery's power.
Last night (heading into today's workday) my phone died completely from a dead battery. I plugged it in and played with it for a while before going to sleep. Before I knew it, the charge light was green. So I powered down and charged it overnight with the phone
off. When I got up this morning, I unplugged it for 10-15 seconds, then plugged it back in. The charging light was red. I waited for the light to turn green again (about 20-30 minutes). Then I power cycled (turning it on and off again) and repeated the process. This time the light was orange when I plugged it back in. I didn't have time for the light to turn green again. But the battery life is much, much better than I was getting with the stock battery.
Right now my battery is sitting at 71% (according to BatteryTime Lite). I haven't plugged it in since leaving the house this morning and I'm looking at an Up Time of 6:44:20 and an Awake Time of 2:20:19.
Sorry, no pictures to post. What would I take them with? My phone is the only camera I have with me and I'm not going to advertise the fact that I'm putting this much thought into my personal phone's battery life on company time.
Soon - maybe this weekend, I'm going to put the stock battery back in and see how it does after a bump charge.
Conclusion:
This battery is better than stock but not twice as good. For $15, I'd buy from BidAllies again in a heartbeat.
