Why does 4g drain the battery

I believe for 5G it is worst, mainly with mmWaves. Hello experts. BR, Rafael. BR, Carlos. As we discussed above, the constant searching of a signal on your device consumes more battery. Summing up the things, for saving the battery backup on your device always try to stay connected to an active WiFi network for best results.

Whenever you find that the WiFi connection is not stable and the signal is weak, you must disable the WiFi network on your mobile. Lastly, when you are travelling and not in a range of any connection, enable the Airplane Mode to save more battery power. There is no doubt that although today's smartphones are well-powered, you will notice that being in a 4G area will have an unavoidable impact on the battery life of your phone.

Obviously this varies from handset to handset, because battery size and processor speed play a part, but the one consistent observation is that 4G activity can be a bit of a drain. This means that when you enter an area that isn't covered by 4G, or you head indoors and lose signal, your phone will constantly be trying to find the nearest 4G network.

The same issue can arise with 3G, although the impact is lessened because 3G coverage is obviously much more widely available. When it comes to downloading files, playing games or streaming video in 4G, you will find that battery life is impacted. Testing unless done in a professional setup is pointless, especially user testing. I am looking for pointers atleast — beeshyams.

So depending on coverage, you'd rather lock it down to 3G or even 2G then. Add a comment. Active Oldest Votes.

So actually you can't feel any difference between 3G-4G energy usage. Improve this answer. The linked articles do not differentiate between using the phone without using data as asked in the question or using voice and data agreed, it fits not say so explicitly buy that is the connotation, when you read the links mentioned.

Use case in question is leaving the phone in 4G without using data at all. I am looking for answers staying this concern — beeshyams. Uttam Uttam 1 1 silver badge 2 2 bronze badges.
