LTE draining more battery

Ok someone make me understand why my battery drains out faster when I use 4G LTE as compared to HSPA. Is there a work around?

Which phone are you using? If it has an MTK chip, that might be the problem.

Lumia 640 XL, Qualcomm Snapdragon 400 processor, could it be the cause?

Have you upgraded the software?

Yea, been on the latest Insider Preview builds for long, the latest one being build 15240. Thought it was a build issue so I reverted to the Creators Update 15063 which is more stable, but the battery drain on 4G is still the same, it’s faster than on 3G

There is an issue with battery drain with the current updates. That must be the issue. But also, keep in mind this is a 2015 device and 4G and battery drain are issues that were not well addressed two years ago.

I think your 4G reception is not good.

Think about this for a moment…

4G is super fast so it has to send and receive tons more packets than 3G. Therefore, to achieve this it must ensure the best possible link to the cell tower. If the signal is not optimal, the phone MUST increase power to the antenna hence the battery drain.

Maybe i just need to get a newer device

or try locking network to 4G only.
Some devices drain battery more when network selection is AUTO

4G processing draws more power. If you want the best battery life for your phone, get a portable external 4g hotspot device, e.g. the ones from Huawei, then let your phone use just wifi. Your battery will last much longer.

You thought that?! Seriously?! :face_with_raised_eyebrow::thinking:.

Think about it, with 4G your phone has to use its antenna to connect to a booster that’s probably kilometers away to get a good enough signal to send and receive tons of data. With Wi-Fi it only has to worry about staying connected to an access point that is a stone-throw away from where you’re sitting. It doesn’t have to raise and lower antenna power with Wi-Fi as it does with 4G because the factors affecting Wi-Fi signal are pretty much constant thanks to your proximity to the AP.

True, but it will never be as low as Wi-Fi. From what I am seeing even 5G will be less of an energy hog than 4G (probably because they’re going to use numerous transmitters for 5G).

I agree with this,LTE radio seem to be drawing more power on my phone but its way better than switching to 3G esp in urban areas.
