Degraded battery ?
I've bought a One X+ second hand and the guy that sold it to me said it was only 2 months old. I have reasons to believe he was telling lies.
Here are some screenshots from Battery Stats Plus:
I've only used the GPS for like 3-4 minutes (not using google maps) and Google Maps separately (no GPS) for 3-4 minutes total. I don't know why it shows a big % on battery usage from Maps. Also the battery history from Settings said that I had the GPS on all the time even thought it was turned off.
DS Battery Saver was also turned on (Gentle profile) so it would go to sleep when screen is off.
I generally can barely manage over 24 hours on a single charge (normal usage, 2 hours of on screen time).
When it's sleeping (all communications turned off) i'm usually losing 1% of battery every 45 minutes. Another thing: the last 15% of battery drains in 3-4 minutes when using the phone (browsing, etc).
Is my batery ok ? I think the device's older than 2 months when I bought it because my older Sensation XE could easily manage over 1d6h normal usage even after 1 year.
