How to choose beyond the mAh figure
Look for comparable battery-life evidence
mAh describes battery capacity, not how long a phone will last in your hands. Screen type and size, chipset, software, signal conditions and workload all affect consumption. Prefer reviews that explain their battery-test method or describe usage clearly, and compare results only when the tests are reasonably alike. The available shortlist does not establish one controlled endurance result for every model.

Judge charging by time, not watts alone
Wattage is a rated charging figure; it does not by itself tell you how long a full charge takes. Gadgets 360 reports that the P4 Power takes nearly two hours to charge fully despite its 80W rating. If you often top up between outings, check an independent full-charge test and whether the included charging setup meets your needs. Gadgets 360 July guide

Check size and comfort in the exact model
A large battery can come with a chunkier handset. If you use your phone one-handed, carry it in a small pocket, or hold it for long gaming or reading sessions, check the exact variant’s weight and thickness in its specifications and, where possible, handle it before buying. The P4 Power is specifically described as chunky by Gadgets 360. Gadgets 360 July guide
Match the display and performance to your workload
The shortlist includes both LCD and AMOLED screens. For example, the listed Tecno Pova Curve 2 has an AMOLED panel, while the OnePlus Nord CE 6 Lite and iQOO Z11x have LCD screens. Consider whether you prioritise display characteristics, outdoor viewing, gaming performance or everyday responsiveness, and look for credible reviews of the exact model rather than inferring performance from battery size. 91mobiles listing

Decide which trade-offs you will accept
A battery-first phone can be the right tool for long days away from a socket, but capacity should not override the features you rely on. Gadgets 360’s assessment of the P4 Power flags its cameras and performance as areas that only just meet expectations. Give camera quality, software experience and day-to-day speed their own weight in your decision rather than treating the largest battery as an all-round verdict. Gadgets 360 July guide
Verify the exact variant and total cost
Before checkout, confirm RAM and storage, seller, warranty and the current total price. The same phone’s listed price changed between the July and October guides, and listing prices do not guarantee stock or a particular seller’s terms. 91mobiles listing; Gadgets 360 price list
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which option fits your priorities?
- Choose the realme P4 Power for capacity first: its listed 10,001mAh battery leads this group, but accept its reported bulk, long full-charge time and camera/performance compromises.
- Consider the Tecno Pova Curve 2 for a lower listed price and 8,000mAh: its listing also identifies an AMOLED screen; weigh that against the other specifications and reviews that matter to you.
- Compare the 7,000–7,200mAh models for a different balance: the iQOO, OnePlus and Motorola listings offer substantial capacities, with LCD panels specified for the iQOO and OnePlus. Check review evidence and exact specifications before deciding.
For a broader view of how reviewers assess phones in this price range, MySmartPrice says its evaluation considers CPU/GPU, storage, display, battery, cameras and overall experience—not battery capacity alone. MySmartPrice guide and methodology
