Ii. Iphone 12 series, battery state critical
The iphone 12 series carries the a14 chip, which is better than iphone 11, but also has 4gb memory limitations
For light users, upgrading does not necessarily have a significant burden
However, the problem of heat and electricity consumption may remain apparent if short videos, navigation, photographs or games are often painted。
The key here is battery health. If it's less than 80%, no blind promotion is recommended
If it's less than 85%, caution is recommended
Since system optimization can only improve movement, it is not possible to compensate for the continuation of the panels resulting from the ageing of the batteries themselves。
Iii. Iphone 13/14 series of experiences that may be polarized
The basic performance of the iphone 13 and iphone 14 series is still adequate, but the experience of upgrading is highly dependent on the battery state。
If the battery is healthy above 85 per cent, improvements in on-site power consumption, temperature control and backstage stability may be felt after upgrading
If battery health is already low, upgrades may lead to a feeling that the previous course will be less advanced and that the heat will become more pronounced in the scenes of games, filming, navigation, etc。
To put it simply, the battery is fine
It is clear that batteries are ageing and it is recommended that batteries be replaced or continue to watch。
Iv. Iphone se3, more stable than iphone 11, but not short board
Many compare iphone se3 with iphone 11, but the core configuration is not the same. Se3 carries a15 chips, performance and energy efficiency are better than a13 and support 5g, so it is more comfortable to face new systems。
However, the screens of se3 are small, single-screened, and continue on a less powerful basis, and if you are a heavy user, then upgrade it in conjunction with your usage habits. Upgrading may be considered for users who use it lightly and are sensitive to security updates; if a continuation is felt to be inadequate, it is suggested to observe first。
V. What types are more suitable for upgrading
From the current feedback, iphone 14 pro and the updated pro package are more suitable for upgrade
They are better off in performance, heat dispersion, high-brush scheduling and backstage management, and are more likely to experience optimization in fluidity, signals and continuity。
The iphone 15, iphone 16 standard version may also be considered for upgrading if the battery is healthy. For these new models, ios 26. 5. 2 is more like a stability supplement。
Six. What if i feel like i've been upgraded
Precautions can be drawn, with large versions or phased updates, and the system usually carries out such tasks as indexing, photo-processing, backstage synchronization and, in the first 1 to 3 days, increased power consumption, heat or mild cartons, which do not necessarily represent a long-term experience of variability。
It is recommended that wifi be connected and charged for one night, while opening the settings-assisting-dynamic effects-dividing the dynamic effects to reduce the burden of visual animation appropriately
Iphone 15/16 users with a new pro type, high battery health, could consider upgrading
Iphone 13/14 users view battery health decisions
Iphone 11, iphone 12 and users with a significant ageing of batteries suggested to wait and see
Upgrading the system is the surest version if it is not as fast as possible and fit for its own。
