I have been able to try the Realme GT 7one of the first phones in the market (generalist, no gaming) with 7,000mAh battery. A full -fledged mobile with a battery whose duration is good, but not superlative. The point is that this is not the first time something like that happens to me.
I have tried mobiles with 4,500mAh batteries that lasted a lot more than others with 5,000Mah. Mobile with 5,000MAH with completely disparate durations, and then we have Apple with a 4,600mAh battery that lasts more than some much larger. Not everything is the ability.
Welcome is the ability. Between 7,000mah and 5,000mah I have it clear: big horse. A battery with greater nominal capacity, to equal optimization and consumption of the components, is a battery aimed at having a longer duration.
A clear example is the Samsung Galaxy S25 Edge With its 3,900mah battery. Miracles do not exist and, with that capacity and the screen of a Galaxy S25+I was destined to have a battery that lasts little.
Android is very Android. Android is a relatively free system, and this has as many advantages as inconvenience. There is nothing more efficient at an energy level than an AOSP ROM, based on “Pure Android” and with hardly any background processes. The issue is that manufacturers want to put their icing: customization layers.
Although they provide added value, starting to build on Android is not simple, and adding both applications and extra processes, sometimes, does not work out. If a version is not optimized, it will devour resources, have the physical battery that the device has.
There are even more elements. To the optimization that each manufacturer has to do in the system if you want the ROM to work well, you have to add that each phone element (screen, modem, Bluetooth, Wifi), has its associated controllers. A bad optimization or adjustment in the software that manages basic hardware elements can translate into triggered consumption.
And, beyond optimization, hardware elements themselves can consume more or less. There are more or less efficient screens, there are more or less efficient processors, thermal management … The cocktail to create a mobile with a battery that lasts what must last is complex.
The solutions. Sometimes, it is best to admit that there is no solution. If your mobile lasts little because milliamps are missing, there is no way out. In the opposite case, there is hope. If a telephone has a brutal battery, but it does not last enough, it is necessary to know the manufacturer to work in an update that solves it.
It is not something, unfortunately, too common. But it is neither the first nor the last time that a phone does not work as fine in launch and, within a few weeks, it all starts stabilizing. In fact, this is not just an Android problem, although the system is more prone to these instabilities in the battery.
I still remember The terrible battery of the iPhone 12 Pro. Yes, he had “only 2.815mah”, but the iPhone 13 pro lasted much more with 300mAh more. Super -healing problems, a total (health) capacity that touched 80% in just one year of use …
