The HTC One does have a bigger battery than many smartphones, rated
at 2,300mAh, and some owners have been complaining that it takes a long
time to charge. You may be used
to your smartphone being fully charged
within three hours, but the HTC One is likely to take four hours or
longer. Apparently HTC has taken precautions to ensure that the battery
lasts (since it isn’t removable) and this partly
accounts for the longer
charging time. If it seems to be taking a lot longer than that then
there are a couple of things worth checking.
Possible solutions:
- Are you using the charger that shipped with the phone? If you’re using an older charger or plugging it into your computer via USB to charge, then it will take longer. If you are using the charger that came with your HTC One, then you might try a different charger, just to make sure that the original isn’t faulty.
- Have you got a lot of apps running on the phone while it is charging? The less that’s active and syncing, the faster the phone will charge.
