As the title says, I too am running into some battery trouble (shocker, I know). I'd like to point out that first I did my research in the HOW+ forums + faqs. So, here's the situation:
Today with 80% of battery i played sonic dash for 45min. After that It shows 40% left. I shut down the phone. Put it in the freezer for 5mins (why not?) then turned it on again. Then it shows less than 16% at startup.
Two weeks earlier i used Navigon gps for 1hour on a full battery, after that i had 50% left. Restarted the phone and it showed 40% and afterwards started going down fast as hell in 1 hour without me turning the screen on. Seriously, at the end I had the 4 low battery alerts in a quick row (14%, 9%, 3%, 1% and then shutdown in 5-10minutes).
I bought the phone in march and used it heavily at first. I was all about thd games (which all push the phone to its limits) + occasional big downloads + uzipping heavy files. Then later i calmed down and mostly used the phone in the evenings before sleep: loads of browsing + youtube + emulators (which, all three combined, don't drain the battery that much even after a long time).
The phone has been rooted for 1 month. I'm still on stock rom. I greenified most of the processes (like every apps and games except viber, tango, whats app skype, line, twitter, facebook, vine) and froze (with titanium backup) google+, gmail,chrome, htc tips, play books, play movies, play kioske, play music, htc tips, htc watch.
Here is my question : do you guys think i should try some battery recalibrating or should replacing the battery do the trick? Or maybe there's nothing to do and the one x+ is just doomed in that area.
In one month I am going to Japan for a couple of weeks and I'll be needing a lot of my HOX+ so I sure wouldn't want to spend money on a new phone (with the next gen devices right around the corner) or on a pricey mugen external juice case. Any piece of advice or info is welcome.
Thanks in advance for your time guys.
