Temperature: Duracell Powermat vs Samsung Wireless Charger

[jimbl]

Does anyone else use both a Duracell Powermat and the Samsung Wireless Charger? I have the Powermat at work and the Samsung at home. I've noticed the Powermat makes my phone noticeably warmer (almost hot) than the Samsung charger. My understanding is temperature plays a large role in battery life (extreme temps high or low). Is anyone else with both these chargers noticing the same temperature difference? I do have two of the Powermats, so I may try the other one to see if the results are the same. If so, I'm considering not using them, without a removable battery I'd rather not risk greatly reducing the battery life.

i'd stick with OEM Samsung.

You can use battery monitor widget or similar to monitor battery temperature while charging. Of course it will be cool after being fully charged some time ago

Yeah I'm using mine at work and can check it periodically.

That's likely what I'll do. I'm going to test the other Powermat first though. If it also makes the phone noticeably warmer, I'll move on.

Good idea. I'll get some numbers and make an informed decision. Thanks.

I used GSAM Battery Monitor and this is what I found:

Started charging at 1:40pm.

1:40pm 75 degrees 62%
2:02pm 85 degrees 75%
2:16pm 88 degrees 82%
2:40pm 86 degrees 95%

The GSAM temperature graph confirms the drop in temp late in the charging. Not sure what's going on there? I'm going to run a similar test on the Samsung charger tonight.

No temperature issues with my OEM charging pad.

Normal as the charging rate drops near the top.

This is from regular(not wireless) charging but it illustrates the point

I did a small test last night on the Samsung Wireless charger:

11:05pm 78 degrees 51%
11:27pm 77 degrees 64%
11:38pm 77 degrees 69%

That seems much better than Powermat. I like your graph better, I downloaded Battery Monitor Widget per your suggestion and will capture better data. Thanks.

Great. So that article says avoid wireless charging and fast charging, two of the "features" of the S6. It's like a sick joke or something.

Because you have both wireless chargers do you find it difficult to find the sweet spot on the Duracell and experience losing the charge and getting the message "wireless charging paused", if so, do you experience the same with the Samsung charger?

Yes, it is difficult to find the sweet spot on the Duracell, and I get the message "wireless charging paused" often. In fact, I stopped using the Duracell. The Samsung charger is much easier to find the sweet spot on, although sometimes does require a few tries, and I never get any "pauses" once it's charging. With that being said, I have since bought the CHOE Stadium Qi Wireless Charger to replace my Duracell, and it's by far better than the Samsung charger also. Every time I put my phone on the CHOE charger, it starts charging. EVERY TIME. If you're interested...
