How to test HTC One X battery life?

  1. Charge battery until 100% fully charged.
  2. Put HTC One X in Airplane mode (Press and hold power button for 3 seconds and select Airplane mode).
  3. Bring up HTC Function Test.
  4. Go to Battery Test.
  5. Follow onscreen intrusions there.
  6. That’s all.

My HTC One X battery is perfectly okay because battery level is still above 70% after running battery test. If yours is not, it’s time for you to send your HTC One X back to service.


  1. In one hour a 12 % decrease is too much and considering it is in air plane mode. How can you say the battery life is ok. I mean i thought my s2 had a poor battery when in one hour with phone and sms sevice on it dropped by 6 – 8%.

    • This is the HTC battery test, this is what they use if you send it back for repair or a DOA claim, not to be confused with actual usage drain. Everything above 30% is acceptable as stated in the test.

  3. hello jayce,

    i tested my htc one x and my battery level reached the limit of 70% after one hour of testing. My battery monitor also indicates overheat after the test. Should i seek manufacturer to replace my device? I only had the htc one x for 1 week.

  4. Hi, I’ve done this battery test 2 times, the first time, I was left with 72% and the second time I was left with 75%. I believe it is too low because in your test you have 88% left. I was down to 88% already after 30 mins. Do I have to seek replacement for my device?
