I didn't see if this was mentioned, but I recently purchased the HTC Rezound for my wife and ordered another battery from VZW for $19.99, I put that battery in my Thunderbolt and it works great. Even with daily usage from medium to heavy, getting at least 14-20 hours of battery life. Iam running a rooted Tbolt and I'm using Skyraider rom and it is great. The phone should have been released with this battery. I have used the bigger extended battery and hated the extra size. Sure it is easy to hold in the hand, but that is just the trade off for having better phone life.
If you love your Tbolt and can't get an upgrade soon, order this battery. You will not be disappointed.
Bxrider117, wanted to reply to your original note in this thread (yes thread police, I know it was posted elsewhere - so WHAT!) to say THANK YOU for letting us know here! I tend to get all melodramatic with this stuff, but you just make probably the single biggest change in my Tbolt experience since the random reboots were fixed. ;-)
My Rezound battery came yesterday. Popped it into the phone and let it charge in the crade all afternoon. Started at about 48% and I got it up to the low 60s before I said naa, I'm gonna charge it in the charger directly when I get home so it's faster. But the slow charge in the afternoon make it "feel" like it was charging more deeply.
Took it home and charged it full. Close to bedtime I popped it back into the phone full, and then still put the phone on the home crade for the overnight.
Woke up and all was well, and with early morning message and twitter checking, the phone sipped on the battery. I kept placing it back on the charger all morning before leaving for work, effectively bump charging it several times.
Here's where I got really impressed.
Left for work. SOP: turn off Wifi, turn on Bluetooth, fire up the earpiece, phone in pocket, out the door.
50 minute drive to work. No calls, but a quick glance for messages, etc, here and there at stoplights. The last few miles of the trip are through the new 4G land of Poughkeepsie NY (due on 12/15, but turned on since 12/12).
I got to my office, turned off Bluetooth and was about to open Tweetdeck when I saw my little battery percent meter go from nothing (100%) down to 99%.
Are you kidding me? That NEVER happens!
After a typical commute I should be down in the low 90s. But I'm only just NOW coming down from 100%?
Fast forward to end of day. Left office a little before 4pm. Now almost 9:30. On batter 5h 30m., at 60%. You might say "big deal" (and maybe it's not for most), but that's awesome performance for my usage habits and signal area, etc (all the factors that impact). At this rate I would be able to get 10-12 hours straight on a single charge.
This Rezound battery is amazing. Very, very impressed. Granted, this is only my first full day of testing, and we know that battery life does improve after the first few full cycles, so I expect it to get at least a little better.
I know folks around here can see better battery performance with other setups, but I'll tell you, this Rezound 1620 is doing better for me than both the default TB 1400 and the Anker 1700 - hands down. And today I went and ordered one for my son's TB.
The improvement this battery will bring will get debated for a while no doubt, but there IS an improvement - no doubt about that.
Many thanks for letting us know!
